SaveAs/SaveACopy dialog windows fail to draw -- are blank gray

See attached screen shot. I'm running Ubuntu Lucid 10.04 (up to date on all packages) on an HP 1224nr Pavilion Laptop running Linux 2.6.32-22-generic #36-Ubuntu SMP x86_64 GNU/Linux. MuseScore: Music Score Editor; Version 0.9.6; Build 3145. Note that running mscore -o works! So the functionality is there. It's just the dialog window that doesn't draw successfully. I can press ESC, RETURN, or click on the window title-bar close button and exit the SaveAs window and MuscScore continues to function well.

Two things of note. I noticed this behavior immediately after updating to Lucid 10.04 in early May. It was *fixed* when I next did the regular Ubuntu update which included a musescore update. But today the draw issue is again happening. Also, mscore.real stays in memory after program exit and consumes lots of cpu:

PID USER      PR  NI  VIRT  RES  SHR S %CPU %MEM    TIME+  COMMAND                 
7617 nak       20   0  590m  97m  37m R   94  2.6  25:52.40 mscore.real
1221 root      20   0     0    0    0 R   58  0.0  58:07.36 ipolldevd

Acutally, it consumes lots of cpu when running as well. Don't know if that has anything to do with the SaveAs window drawing, but figured I'd toss it in anyway.
