I wrote an application with matplotlib, which often (3 times a second or
more) updates the graphics window. When I switch off the update, the
aplication is quite stable, but with updates Xlib prints the following
lines and the application freezes.
Xlib: unexpected async reply (sequence 0x1318f)!
Xlib: sequence lost (0x20000 > 0x1318f) in reply type 0x0!
I do not know how to debug/backtrace this message. Does anyone have a clue?
The application is using matplotlib with pygtk and numarray, running
under Debian testing.
It is not clear to me, if this error is caused by matplotlib, but it
seems to be "correlated" to its use.
Any help is welcome.
