Description András Manţia 2008-05-19 16:31:48 UTC

The progress bar shown "foldername: Checking permissions" for some seconds and
after that it crashed. BT:

Comment 1 András Manţia 2008-05-19 16:32:29 UTC 
SOrry, copy/paste from http://rafb.net seems to not work correctly..
Comment 2 Jean-Baptiste Mardelle 2008-05-20 00:46:23 UTC 
Not sure it is the same bug but I am experiencing similar problem: disconnected IMAP in svn trunk stopped working correctly about one week ago. Mail checking always hangs with message:

Checking folder validity

If I try to stop the task from KMail's progress list, it crashes with following backtrace:

Comment 3 Jean-Baptiste Mardelle 2008-05-20 17:22:00 UTC 
The hanging problem was fixed by commit #810351 
( http://websvn.kde.org/?view=rev&revision=810351 ).

For me the bug can be closed.
Comment 4 FiNeX 2008-06-21 11:52:46 UTC 
@Andras: did you have still crash using recent revisions?
Comment 5 András Manţia 2008-06-21 22:01:34 UTC 
No, I did not see this lately, let's close it. Thanks for reminding me about.
