Version: 3.1.3 (using 4.1.3 (KDE 4.1.3), Arch Linux) Compiler: gcc OS: Linux (i686) release 2.6.27-ARCH In Kate editing C source files. If I have a whole function folded and I try to delete it, by selecting its lines and pressing canc, Kate crashes immediatly. To avoid the crash I have to unfold the function, select its lines and then canc.
If you can reproduce the crash at will in a recent KDE (4.1.3 /4.2beta2 /4.2svn) , can you read http://techbase.kde.org/Development/Tutorials/Debugging/How_to_create_useful_crash_reports and post a complete backtrace here? Thanks :)
The crash doesn't show the Crash Dialog so I used gdb. I guess I should get more debug informations. I use Arch Linux. Do I have to recompile something with '-g' ? I'll ask in Arch forums. gdb kate GNU gdb 6.8 Copyright (C) 2008 Free Software Foundation, Inc.

This may be related/duplicate of bug 177790
Fixed in r904337. Deletion of folded and nested folded regions works now. If this bug reoccurs reopen. There are some existing issues with updates of folding regions, which don't have bugreports I'll try to fix them during the next days or at least for 4.3
