I discovered recently that my mod+q is not working correctly. When I press it it kicks me out and I have to login again, this crashes all the programs I'm using etc. I am using xmonad 0.9.1 on xubuntu 10.4. I installed xmonad with the package manager, and this happens on a fresh install with the default xmonad.hs. I don't think it has anything to do with the xmonad.hs file I use, but just in case it can be found at http://hpaste.org/74925. I also did a [2] ptrace on xmonad while I pressed mod+q which makes it look as though xmonad is sending garbage parameters to itself (thanks to geekosaurus on irc for this). Here is the portion where I think stuff starts to go wrong, but the full trace can be found at http://hpaste.org/74927.

write(2, "xmonad: ", 8) = 8 write(2, "user error (unrecognized flags)", 31) = 31 write(2, "\n", 1) = 1 getrusage(RUSAGE_SELF, {ru_utime={0, 984061}, ru_stime={1, 24064}, ...}) = 0 gettimeofday({1347995657, 921071}, NULL) = 0 rt_sigprocmask(SIG_BLOCK, [INT], [], 8) = 0 rt_sigprocmask(SIG_SETMASK, [], NULL, 8) = 0 timer_settime(0, 0, {it_interval={0, 0}, it_value={0, 0}}, NULL) = 0 timer_delete(0) = 0 rt_sigprocmask(SIG_BLOCK, [TTOU], [], 8) = 0 rt_sigprocmask(SIG_SETMASK, [], NULL, 8) = 0 rt_sigaction(SIGINT, {SIG_DFL, [], 0}, NULL, 8) = 0 rt_sigaction(SIGPIPE, {SIG_DFL, [], 0}, NULL, 8) = 0 getrusage(RUSAGE_SELF, {ru_utime={0, 988061}, ru_stime={1, 24064}, ...}) = 0 gettimeofday({1347995657, 928425}, NULL) = 0 munmap(0xb7500000, 1048576) = 0 exit_group(1) = ? Process 410 detached

Mod+q is mapped to the default of "spawn "xmonad --recompile; xmonad --restart"", and a xmonad --restart executed from the terminal leads me to believe that this is failing somehow, but I have no idea how to find out more or to fix it. Thanks for your help.
