Comment 1 Milian Wolff 2011-09-08 10:36:05 UTC 
kate bug - should also happen inside Kate/Kwrite. Can you reproduce this? If so, please run the app through valgrind and show us the log it produces:

valgrind --track-origins=yes --num-callers=25 ...

bye
Comment 2 Dominik Haumann 2011-09-09 13:11:56 UTC 
Tomasz, can you please reproduce the crash when running Kate in valgrind?

Looking at the backtrace: #16 - #24 and #35-40 are very similar.
Looks almost like a recursive call:
#16 KateBuffer::doHighlight (startLine=279, endLine=343, invalidate=true) at katebuffer.cpp:503
#17 KateBuffer::ensureHighlighted (line=279) at katebuffer.cpp:252
#18 KateDocument::kateTextLine (i=279) at katedocument.cpp:4775
...
#35 KateBuffer::doHighlight (startLine=279, endLine=343, invalidate=true) at katebuffer.cpp:715
#36 KateBuffer::ensureHighlighted (line=279) at katebuffer.cpp:252
#37 KateDocument::kateTextLine (i=279) at katedocument.cpp:4775

line=279, startLine=279, endLine=343 are the same. Maybe this is helpful?
