This happens after I give both imaps passwords.

kdepim-4.2.3-1.fc10.x86_64

This comes to stdout when it crashes:

Program received signal SIGSEGV, Segmentation fault.
[Switching to Thread 0x7ffff7fa8810 (LWP 5110)]

(gdb) <unknown program name>(5104)/: Communication problem with  "kmail" , it probably crashed.
Error message was:  "org.freedesktop.DBus.Error.NoReply" : " "Did not receive a reply. Possible causes include: the remote application did not send a reply, the message bus security policy blocked the reply, the reply timeout expired, or the network connection was broken." "


I've something else fishy in dbus as that also causes plasmoids/applets to hang.

Another attempt with different source line:
Program received signal SIGSEGV, Segmentation fault.
[Switching to Thread 0x7ffff7fa8810 (LWP 5238)]
QTreeWidget::setItemExpanded (this=0x31, item=0x2a78640, expand=false) at itemviews/qtreewidget.cpp:3112

(gdb) <unknown program name>(5235)/: Communication problem with  "kmail" , it probably crashed.

+the dbus error.

The backtrace looks related to bug 184324. Thanks
