Narrowed Time Frame 3/29->4/3 kwrite crash -> Looks like Qt3 bug

From: "David C. Rankin" <drankinatty@...>
Date: Tue, 01 May 2012 14:12:14 -0500
Tim, Darrell, All,

   I rebuilt all packages this morning with sources from 4/3 to help narrow 
down the kwrite crash issue. The files were built with full debug information. 
I don't know if this new backtrace is useful, but it is different from the 
prior backtraces in that it points straight at tqt3. (at least to me) I can't 
interpret exactly what it is saying, but I'll let the experts decide:

Backtrace stopped: previous frame inner to this frame (corrupt stack?)

   A strace was also run and I've attached that to bug 979.

http://bugs.pearsoncomputing.net/attachment.cgi?id=576

   I also get a lot of undefined symbol messages when strace is running. I 
don't know if this will help, but maybe it provides a clue. IIRC, there was a 
name mangling patch that went it at some time around here. This is what gets 
dumped to konsole:

   I also tested kate - same crash! I don't know what Darrell is doing, he 
must be living right! I just pasted 'undefined symbol ' into line one until it 
would make it wrap and then on the next paste - wham! > crashed. This 
backtrace is a bit different, the qt3 error I saw in kwrite appears masked for 
some reason?? Here is the kate crash backtrace:

   What say the experts? Anything look like it points to anything specific? 
Worth running a strace on kate?

   I also found another bug in the setup wizard when choosing keramik style -- 
you get no window decorations. (this may be fixed since this was the 4/3 
code). Plastik works fine. I had deleted ksycoca and my ~/.trinity profile for 
this test, so I was starting over from scratch. I thought I would pass that 
along as well.
