Description Will Angenent 2009-01-14 23:37:49 UTC 
Version:           v3.2.60 svn r910563 (using Devel)
Compiler:          gcc version 4.3.2 (Ubuntu 4.3.2-1ubuntu11) using kubuntu 8.10
OS:                Linux
Installed from:    Compiled sources

Sorry to say I hit an assertion failed:
  // If you hit this assert, it is a fundamental bug in katepart.  A cursor's
  // position is being set beyond the end of the document, or (perhaps less
  // likely), in this class itself.
  //
  // Please figure out how to reproduce, and report to rodda@kde.org.
  Q_ASSERT(smartGroup);

I was editing a cpp file with static wordwrap turned on and repeatedly copy pasting a block which was being wrapped automatically. I was being silly and hadn't realized static wordwrap was on. Something strange was happening, because I was pressing delete at the start of a second wordwrapped line, which should have deleted the previous character, but nothing was happening. After a couple of minutes of banging my head against the wall, and lots of copying pasting of the same piece of text, I used the arrow key down to go to the end of the document, and that's when kate crashed.

I tried to reproduce, but haven't been able to. I'll keep trying...

Will

Thanks for the report, but without way to reproduce it, no chance to fix :(

I just hit that assertion twice.

A file got changed outside of kdevelop, I switched to that tab, kdevelop asked if I want to reload and then got the crash. The file didn't change a lot (as in a few of 2500)
