Description sombragris 2004-01-27 19:27:55 UTC 
Version:            (using KDE KDE 3.2.0)
Installed from:    Slackware Packages
OS:          Linux

I was using Kontact with the KMail plugin. I had the Composer window open and I was trying to change the spellchecker language. After clicking OK there was a small dialog telling me that the settings would be applied only after closing and reopening the window, and then Kontact crashed and I lost an important email message in composition. Kontact in this case is a zombie, and you have to manually kill the process.

I can confirm this bug occurs for me too. Fortunately I didn't lose anything important.
Comment 2 Daniel Molkentin 2004-07-06 00:09:18 UTC 
Confirmed to happen with standalone KMail, too. Backtrace with debugging symbols:
