[Kolab-devel] [issue3273] kmail hangs connecting to itself

Marc Mutz kolab-issues at intevation.de
Thu Nov 27 11:34:37 CET 2008 

New submission from Marc Mutz <marc at kdab.net>:

It's nearly 100% reproducible when starting kmail from the build dir. This is 
with the kolab resource provider set to kmail, not kontact.

To reproduce (composer):
1. start kmail
2. more of less immediately hit CTRL-N
3. start typing in the To field
-> hang

To reproduce (reader):
1. start kmail
2. more or less immediately go into a folder with mail
-> hang

Workaround I found:
1. start kmail on a folder that does not contain mail
2. change between a couple of folders without mail
3. do anything
-> no hang
