$ gdb /opt/wine/bin/wineserver `pidof wineserver` Excess command line arguments ignored. (206788)
this means two instances of wineserver were running. (gdb attached to first one and reported second). Did gdb pick up the right instance?
no crash from log, so no need go further with gdb... need more perusing of the traces
