Description Patrick C. F. Ernzer 2007-11-13 12:50:12 UTC 
Description of problem:
kmail will crash sometimes if connectivity is lost at the wrong moment. This is
really annoying for users who are on a flaky link (say UMTS on a train).

Version-Release number of selected component (if applicable):
kdepim-3.5.4-4.fc6

How reproducible:
takes a while but will eventually crash

Steps to Reproduce:
1. start kmail
2. make sure you have an IMAP server configured
3. set the check mail interval to 2 minutes
4. run the following in a root sheel to simulate flaky link
# while true; do echo down;ifdown eth0;sleep 15;echo up;ifup eth0; sleep
30;date;done
  
Actual results:
eventually kmail will crash, I've had runs where this reproducer crashed in less
than 10 minutres and runs where it took > 30 minutes (at which point I went home
for the night to find it crashed in the morning)


Expected results:
A mail user agent needs to be able to deal with connectivity loss without crashing

Additional info:
I've installed kdepim-debuginfo-3.5.4-4.fc6.i386.rpm to get a decent backtrace
from the kde crash tool. Do tell if you want further tests run.
