Hmm. Strange bug. I'm unable to duplicate this in the way you described, but there is definitely something wrong. Valgrind indicates a problem in kdelibs, but it may just be that we're using that class incorrectly. I'll look into it some more when I have more time. I need to look at the Undo/Redo stuff, as well.
Nicholas, could you open a bug report and attach your backtrace? I wonder if we need to check whether m_passivePopup is non-NULL before we delete it? It would help if you could run basket under gdb and set a break point at line 2313 of bnpview.cpp. Then let me know what the following variables are set to (they are pointers, but if you give me the addresses in hex I can get a pretty good guess at whether they are NULL, point to something deleted, etc): m_passivePopup Global::systemTray Thanks!
