Comment 1 Dario Andres 2009-06-26 00:11:33 UTC

As you can reproduce the crash at will, may you read http://techbase.kde.org/Development/Tutorials/Debugging/How_to_create_useful_crash_reports and post a complete backtrace here? Thanks

Comment 2 Jeff Shaw 2009-08-20 01:31:54 UTC

I just compiled Kate 3.2 from sources on Mac OS X 10.5 using Apple's gcc 4.0.1. The build was handled by MacPorts. When quitting Kate I also get SIGSEGV. The crash does not happen if I merely open Kate and then Quit instead of opening a session or making a new one. Here is the info from the bug program that ran when it first crashed.

It crashed again and gave slightly different details:

The KDE bug catching program doesn't always run. This is the info from Apple's equivalent. The next post is the backtrace from when run in gdb.

Comment 5 Dario Andres 2009-09-04 16:38:03 UTC

@Jeff Shaw: sorry about the trouble, but, could you please put all the information you gathered in a new report ? The policy here is one report per issue, and we can't be sure your crash was the same as the originally reported. Thank you very much.

Comment 6 Arun 2009-09-05 06:22:17 UTC

Still this issue is not resolved :-(

I have put the full backtrace this time. Pls help

-------------------------------------------------------------------------
Unable to create a valid backtrace.

This backtrace appears to be of no use.
This is probably because your packages are built in a way which prevents creation of proper backtraces, or the stack frame was seriously corrupted in the crash.
