Public bug reported: There is a bug in at least xorg-server 1.7.6 (as shipped in Lucid) where certain uses of XTest cause a null pointer dereference and the server crashes.
XTest probably isn't used much in general, but this causes very serious problems for 'xpra' -- basically it is unusable in Lucid (at least for me) because the X server keeps crashing under it. I would not be surprised if x11vnc had a similar problem. (NB, I am the upstream for xpra.) This bug has been fixed in upstream X.org, and I bisected the fix to this commit: http://cgit.freedesktop.org/xorg/xserver/commit/?id=af170a4ab76d33254dd4e54a33bb410fa1624739 This bug-fix commit has also been backported to the 1.7 stable tree, and is included in xorg-server 1.7.7: http://cgit.freedesktop.org/xorg/xserver/commit/?id=ad48184752970541aa153bf2961a2d7da1a910b5 and I have confirmed that xpra works with 1.7.7. Please upgrade to 1.7.7, or apply this patch to your 1.7.6.
