[Bug 558596] [NEW] xorg crashes after switching from tty7 -> tty1 -> tty7

 

Public bug reported:

Binary package hint: xorg

xorg crashes after switching vts from tty7 -> tty1 -> tty7. apport does
not catch anything, though the log shows a backtrace. This only
manifests after X has been running for a while, newly started X does not
crash in this way.
