TQT3 Error

Hi, is anyone using Trinity for Slackware? On my Slackware 14.2, kdesktop is not always loaded, the error seems to be related to tqt3 and the use of utf-8 encoding in the system. This happens when using the smp-kernel, there is no error on the usual kernel. Unfortunately I'm not a programmer and I do not know what can be done. I attached a log, maybe it will help to understand what might be the matter. https://paste.ee/p/mjK6J best regards, Oleg Levenets.
