Serious bug#1493

[Chong Yidong]

If anyone has access to a remote X display, could you try to debug
#1493?  This is a crash in make-frame-on-display for remote displays,
and it's probably the most serious bug in the tree right now.

Thanks.

I can't reproduce it.

From the backtrace it seems that it's using qtengine:

#10 /usr/lib/libX11.so.6(_XReply+0x243) [0x7fea4c616673]                          
#11 /usr/lib/libX11.so.6(XGetGeometry+0x8f) [0x7fea4c5f1cff]                      
#12 /usr/lib/libgdk-x11-2.0.so.0(gdk_pixmap_foreign_new_for_display+0xa0) [0x7fea4fa3eb60]                                       #13 /usr/lib/gtk-2.0/2.10.0/engines/libqt4engine.so [0x7fea48cc979e]              
#14 /usr/lib/gtk-2.0/2.10.0/engines/libqt4engine.so [0x7fea48cc3021]              
#15 /usr/lib/libgtk-x11-2.0.so.0 [0x7fea4fd7b2fd]                                 
#16 /usr/lib/libgtk-x11-2.0.so.0 [0x7fea4fdb8908]                                 
#17 /usr/lib/libgobject-2.0.so.0(g_closure_invoke+0x16d) [0x7fea4dea825d]         
#18 /usr/lib/libgobject-2.0.so.0 [0x7fea4debdc3b]                                 

and AFAIR we've had bugs in the past that were actually due to qtengine,
and not bugs in emacs.
Maybe ask the OP to try to reproduce the problem with another theme...

Neither can I BTW.

Now that makes a lot of sense, thanks.

OK, that makes sense.  I'll downgrade the severity to normal, then.
