Minimwatch Crashing

[Budgie]

Hi Simon,
Trying to run minimwatch on openSUSE machine. It used to work OK but now it starts and immediately crashes with the following message:-

[undefined=~/minimwatch-0.63/data> java -jar ../lib/minimwatch.jar
MinimWatch 0.63, Copyright © 2012 Simon Nash. All rights reserved.
Startup complete - press enter to shutdown:
MinimServer[qnapnas1] is running
The program 'java' received an X Window System error.
This probably reflects a bug in the program.
The error was 'BadMatch (invalid parameter attributes)'.
(Details: serial 390 error_code 8 request_code 73 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.)

I am uploading new data to server so that might be cause of problem but seek your advice please.
