Look like another mono problem

[jng]

Does running mono with "--debug=casts" give more information?

Yes, it told the failed cast:

Somewhat reproduced also on mono trunk - version 2.11.5 (master/1be50d0 mer 12 set 2012, 15.42.47, CEST)

When scrolling "Available Commands" panel, it throws an error with the same stack trace posted before, and the pane is replaced by a red rectangle without any content.

It happens the same also with "Custom Commands" panel but not with "Toolbar, Context Menu, Task Menu" tabbed panel on the left, which works correctly.

At least it does not crash maestro anymore.

Fixed r7046

[gabrimonfa]

The "Custom Command" panel now works.

"Available Commands" does not yet, with the same stack trace as before.
