Comment 1 Alex Merry 2010-09-18 15:41:44 UTC 
Unsurprisingly, given the backtrace, it doesn't crash if I delete the desktop file for the sharemicroblog plugin.
Comment 2 Artur Souza (MoRpHeUz) 2010-11-30 14:52:30 UTC 
It's interesting that it's crashing in a completely "non crashable" part of the code. are you running trunk?

Do you still have the desktop file that you deleted? I can't reproduce it here..
Comment 3 Alex Merry 2010-11-30 20:27:46 UTC 
Huh.  It's been working for a while, I guess - I've done a complete rebuild of KDE several times since then.  Must have been a bad build.
