Version:            (using KDE 4.1.2)
OS:                Linux
Installed from:    Ubuntu Packages

Easy to reproduce at my end.

- Start Kontact (from konsole cmd line for this, but same from menu)
- Click New Message button
- Compose new Message Windows appears
- Click in body editor
- Kontact crashes.


The console output shows a problem opening /usr/lib/aspell/bg.multi.
/usr/lib/aspell/bg.multi is a link to /etc/alternatives/bulgarian-aspell-dictionary
/etc/alternatives/bulgarian-aspell-dictionary is a link to /usr/lib/aspell/bg-w_english.multi

/usr/lib/aspell/bg-w_english.multi does not exist!

Also my language is english (Australian). I have no idea why its trying to load a bulgerian dictionary.
