Tim-Christian Mundt commented on JAMES-979:
-------------------------------------------
(Well, I thought an uncaught exception is worth to be written to error out,
that's why I mentioned.)
To "reproduce" (as said, it's not consistent):
1. Start James
2. Open up Thunderbird
3. Click on the INBOX of an IMAP James account
4. See the mailbox getting loaded correctly
5. Close Thunderbird
Most of the times there is no error at all. If I get errors, then it's mostly
this (sorry, for the loads of backtraces here):

which only appears once and than everything's still working. But sometimes I
get this an infinite* number of times:
