Crash when part extracting

Hi,

Using v1.1 : Kubuntu: 64bit.

I get the new part tab appearing in the main window but if I click it musescore crashes

I get the following console output using command line musescore -d, which suggests a bug. Please advise.

Best wishes,
Howard Gilbert

MuseScore::cmd
The program 'mscore.real' received an X Window System error.
This probably reflects a bug in the program.
The error was 'BadWindow (invalid Window parameter)'.
(Details: serial 6144 error_code 3 request_code 20 minor_code 0)
(Note to programmers: normally, X errors are reported asynchronously;
that is, you will receive the error a while after causing it.
To debug your program, run it with the --sync command line
option to change this behavior. You can then get a meaningful
backtrace from your debugger if you break on the gdk_x_error() function.)
