Please Reopen Bug:
Problem persist:
Accessing plenty of IMAP folders over a slow connection or accessing IMAP folders over a slow connection result in a crash.
Happens as a standalone or as a kpart running inside kontact.

The same error and behavior has been observered with Kmail versions from 3.1.x throughout 3.5.7 with downloaded and self-compiled versions (RPMs) on different SuSE Linux versions:
- SuSE 9.2
- SuSE 9.3
- openSuSE 10.1

Error occurs while accessing cyrus imapd from the following locations:
- from work: 100MBit, 1 hop
- from home: 6 MBit, 15-20 hops

System info at home:
KDE Version  KDE 3.5.7 "release 80.1" , openSUSE
Application  1.2.4 (enterprise 20070904.708012)
Operating System  Linux (i686) release 2.6.16.53-0.8-default
Compiler  Target: i586-suse-linux

System at work only differs in the running kernel version, I think it is 2.6.4.something and at work the RPMs are self compiled from downloaded SRPMs.

I observed, that increasing the number of subscribed imap folders exposes a similar/same bug at work, while decreasing the folders at work gives me a working application. We have approx. 70 imap folders (customer an project infos) at work, so I do not need all of them all the time, but it is pretty tedious to unsubscribe to unused folders before subscribing to new ones just to make sure kmail does not crash.

I will attach a tracback from home.
