Summary: Badmatch crash in ServerDialog.h
Initial Comment:
takeFocus() attemts to get the focus even if the window is not mapped. This
causes a crash when the server selection dialog is iconified and receives the
focus. This is 100% reproducable with MWM or 4DWM. This can be avoided by
checking if the window is visible (patch below) or, as qt does in
qapplication_x11.cpp, by using an XSetErrorHandler() that just ignores
BadMatches from XSetInputFocus() calls, e.g. iif (err->error_code == BadMatch
&& err->request_code == 42 /* X_SetInputFocus */) {return 0;}
The error message when crashing is:
X Error of failed request: BadMatch (invalid parameter attributes)
Major opcode of failed request: 42 (X_SetInputFocus)
Serial number of failed request: 527
Current serial number in output stream: 527
