What version of wx widgets (wxGTK package) do you have installed?
wxGTK-2.8.7-2.fc9.x86_64
I can confirm this behaviour on F9 -- but it seems to be caused by wxWidgets, therefore I'm changing the component to wxGTK.
It is questionable what is the primary source of the problem, because there is no problem when I try to run boincmgr on F9/i386. Also boinc* packages have unusable debuginfo, so it is hard to debug.
Luke, are you running an i386 or x86_64 machine? (I'll try to investigate what's wrong with the debuginfo package.)
The source of missing debuginfo is probably simple - strip (resp. @STRIP@) is run when creating/symlinking ".unmodified" and normal binary - see the end of Makefile.am in both client and clientgui dirs.

It happens only on x86_64 -- even installing i386 packages on F9/x86_64 (including all its dependencies, of course) makes boincmgr working. I've fixed the broken debuginfo package (thanks for the hint, I should have noticed earlier that it is so damn small) -- please download the latest build from Koji: http://koji.fedoraproject.org/koji/buildinfo?buildID=48824 So the current gdb output is: (gdb) run The program being debugged has been started already. Start it from the beginning?

From the backtraces #2 and #1 is clear that problem is in boincmgr - #2 calls #1 with this=0x0 (m_SimpleSkin member of the class should be NULL when his method gets called). boinc-manager works on F8/x86_64 + wxGTK-2.8.7-2, so it looks like a gcc 4.3 incompatibility of the boincmgr's sources, switching the component back to boinc-client
Changing version to '9' as part of upcoming Fedora 9 GA. More information and reason for this action is here: http://fedoraproject.org/wiki/BugZappers/HouseKeeping
I see, sorry -- somehow I thought that from #3 down it's wxWidgets code, although SkinManager.cpp is a part of BOINC. Reported into BOINC trac as ticket #658 (http://boinc.berkeley.edu/trac/ticket/658)
This bit me; I got a simplified test case and have attached a fix to the boinc bug. sizeof(int) != sizeof(long) - this should never have worked.... Not sure the best way to get upstream to apply this; I'll leave that with you....
Its been applied upstream.
Great work Bradley, thank you very much! Should be fixed in boinc-client-5.10.45-13.20080315svn.fc9 (http://koji.fedoraproject.org/koji/buildinfo?buildID=49385) An update will come soon.
Yep, that fixes it.
