Bug 177852

Version:           3.1.82 (using 4.1.82 (KDE 4.1.82 (KDE 4.2 >= 20081204)), Gentoo)
Compiler:          i686-pc-linux-gnu-gcc
OS:                Linux (i686) release 2.6.26-gentoo-r1

Today I tried to reproduce bug #157754 and I seem to be able to still reproduce it -- more or less. However, as the backtrace I get today seems to be completely different from the backtrace I got for bug #157754 months ago, I decided to open a new bugreport.

Steps to reproduce:

1) Open a long document with code folding
2) Split vertically
3) Go to bottom of page in right view
4) Click with left mouse button in right view
5) Fold some stuff on the right side (view on right side gets updated accordingly)
6) Right click in right view


The backtrace for this crash is:

Application: Kate (kate), signal SIGSEGV
