This looks like a hard bug to find. I don't think the iconbox code does anythng special. I can only guess that there is a problem between the netk library functions and the window manager and perhaps the twinview stuff, but I don't even know where to start looking :( Thanks for reporting it.
Same segfault here: Program received signal SIGSEGV, Segmentation fault. 0xb7f4e1ea in netk_workspace_activate () from /usr/lib/libxfcegui4.so.4 (gdb) backtrace #0 0xb7f4e1ea in netk_workspace_activate () from /usr/lib/libxfcegui4.so.4 #1 0xb70b9b3c in ?? () from /usr/lib/xfce4/panel-plugins/libiconbox.so #2 0x00000000 in ?? () I am running Gentoo, if you need informations about my installed packages just ask. I have both wxGTK v2.6.4.0-r3 and wxGTK v2.8.7.1-r1 installed
I think twinview can be excluded, I don't have it installed at all. Can it be a bug in wxGTK v2.8.7.1-r1, instead? Did anybody check their bug tracker?
Closing since we've switched to wnck.
