[Bug 48034] Re: kmail crashes on startup

[eocanha]

(sorry for so much continuing...)

I've discovered a crash scenario:

I had the "Folder --> Discussion thread" option activated. I deleted
(SHIFT+DEL) a message that was the first in its thread and had one more
behind it, and that crashed KMail. I restarted the program, repeated the
action and confirmed the crashing.

The next time I restarted KMail, I found the discussion thread option
disabled ¿?, but that thread in particular still showed the tree branch
lines. I activated the option and branch lines and unfolding "+" icons
for more other threads appeared. I disabled the option (all lines and
icons disappeared, ok) and deleted the message. There was no crash at
all.

Maybe there is some bug in the tree widget, or in the data structure
containing the threads. I hope this report can help.
