Hi all,

I seem to have stumbled into two nasty bugs with gtk-qt-engine:

First, I couldn't use gnome's nm-applet because I was getting this error:

"GTK+ 2.x symbols detected. Using GTK+ 2.x and GTK+ 3 in the same process is not supported"

Yes, nm-applet is now using GTK3. Unfortunately the reason it is crashing is because we preload our kgtk library (LD_PRELOAD environment variable). This kgtk library is based upon gtk2. any time those symbols or code mixes, it will crash.

A workaround is to remove the variable and then launch it.

Second, I had been having some problems with Google Chrome where changing the default download directory wasn't working, it simply ignored the directory I selected in the dialog. This seems to also have been causing me a similar problema where e-mail attachments wouldn't be attached.

Since removing qtk-qt-engine to test this hypothesis, everything is working as it should, despite being uglier.

What is worse is that even when selecting what I thought was a GTK3 theme (oxygen-gtk), I still wasn't able to launch nm-applet and there was no option to disable this behavior, though I haven't found bugs like this in the past (and still don't on my Gentoo box running the patched KDE 3.5.10), though I have seen instances where checkboxes aren't rendering Should I submit a bug report or has anyone already found and filled something like this?

Submit a bug report for gtk2 problems only, and the conflicts i mentioned above. A GTK3 engine is on the wishlist but is unlikely to happen anytime soon.
