I was going to commit the patch into git, but comment:
// FIXME (Serghei): i'm not sure about role of "relay"
seems to be very important. I looked into the ambient code. relayEnabled
is switched by decodeContent, hence, depending on the "DECODE" in the
URL. I see a potential problem remove handling 'relay' from
parseReadLine, while in other code is apparently somehow used.
Therefore I believe that the patch needs further research and testing. For
this reason, now I do not expect inclusion into 3.5.13.2.
Any comments or objections?

I guess that the endless-loop on 64 bit systems is fixed by one of François'
patches.
My patch fixed this issue as a side effect, I discovered that kio_imap4 read
lines of stream wrongly (i.e. read one line and half, instead one line at
once) and I tried to address this.

Hello,
I confirm that my own patches were written to solve 2 frequent issues
that I had seen :
- Segmentation fault while parsing imap stream, causing kmail crash;
- Endless loop while parsing imag stream, causing 100% CPU and kmail hang.
(I'm on 64 bit BTW.)
Now kmail does not crash anymore, but I still have issues with imap parsing:
when opening a big imap folder containing "bad" mails (chinese spam,
badly encoded ...), kmail often shows them as "unknown" and "unread"
This is because the imap parser fails.
So when I open my spam folder containing lots of badly-encoded chinese
spam, I see lots of "unknown/unread" messages, but this is wrong. They
are correctly displayed in Thunderbird.
Now, the kio_imap4 fix from Serghei seems to fixes the parsing issues:
now I can browse all my folders correctly in kmail.
So, I think we should push this patch in 3.5.13.2. Without it, I
consider kmail as being unusable with imap (at least: I would not
recommend using kmail without this patch).

It seems that I found the problem of missing 'relay' handling!
I use KOrn for notification. KOrn also uses kio_imap4. With the patch from
Serghei KOrn constantly reported broken connection to a remote IMAP
server. When I revert kio_imap4 to version without this patch, KOrn
working properly.
I would like to incorporate this patch - looks good. However, the problem
with missing 'relay' handling I consider confirmed and necessary for fix.

Yes, you're right, I forgot the parseRelay() call ! Oops !
BTW I now doubt that your Korn problem is related to these patches ...
Are you even sure that Korn uses the "relay" feature ? I'm not.
I've just built and tested tdepim several times :
1) Without Serghei's patch: Korn works correclty
2) With Serghei's patch only: Korn works correctly
3) Serghei + yesterday's patch: Korn works correclty
4) Serghei + corrected "parseRelay" patch : still works correctly.
I have no imap disconnection at all ...
So, my guess is we still don't know really what's the "relay" feature is
for , and all my patches are useless.

For me, the situation is different:
1) Without Serghei's patch: Korn works correclty
2) With Serghei's patch only: Korn is constantly disconnects
3) Serghei + yesterday's patch: Korn is constantly disconnects
4) Serghei + corrected "parseRelay" patch: Korn is constantly disconnects
Probably this is not related with the handling of 'relay'. I looked
into .xsession-errors - no related problems are reported.
Strange for this behavior is that disconnects occurs only for one from the
three dovecot IMAP servers, on which are mails watched.

I have prepared a completely alternative patch! When examining the original

buffer.
This reminded me bug 737 and commit 65c85dca (tdebase). This commit fixes in
the POP3 protocol exactly the same case as in the original code of IMAP
protocol. Therefore, I have prepared a same patch for IMAP (for original
