Version: (using KDE KDE 3.3.1) Installed from: SuSE RPMs Sometimes when I double-click on a search result (Tools->Find Messages) to open a message, KMail simply hangs. CPU and memory usage remains normal, but the KMail program (both the search window and the main window) is completely unresponsive. The windows don't even get repainted. I have to manually kill and restart KMail to regain control. I haven't noticed any pattern as to when KMail hangs and when it doesn't. Sometimes I will try to open a particular search result and KMail will hang, but if I restart KMail and issue the exact same search and double-click on the exact same result, it won't hang. But sooner or later I will end up trying to open a message and it will hang -- I'd estimate perhaps one out of every ten or twenty messages does this. Let me know if there's anything else I can do to help troubleshoot.
Here is a gdb backtrace produced during a hang: #0 0x42532fe2 in select () from /lib/libc.so.6 #1 0x413b2ca0 in __JCR_LIST__ () from /opt/kde3/lib/libgpgme++.so.0 #2 0xbfffd330 in ??

Given that GnuPG-related functions appear in the backtrace, perhaps this is a manifestation of Bug 33372...? (I think every message I've tried to view from the search results was OpenPGP-signed.)
Indeed. *** This bug has been marked as a duplicate of 33372 ***
