  Didn't help.  After Openbox were the last client remaining I restarted
 it too using SIGUSR1, no go.

  No effect.  (I tested that it worked correctly before the hang, too.)

  I have no idea what functionality they provide, they've just been in
 my config file in my years.  :-)  Anyway I removed them (without
 noticing any difference in how the fonts looked), but it did not
 prevent a hang.

  Ehh...  *blushes*

  Anyway, I attached GDB to the X server from the console, put it in a
 screen and attached to it from within X.  When the hang occurred there
 were no signals or anything else showing up.  So that didn't make me
 any wiser either.  :-(
