Since the last update I get a random segmentation fault most often when VO is closing, but occassionally when doing /lua ReloadInterfaces()

OS is openSuse 10.3 Linux

Information in the errors.log file is:

unload interface

Assertion failed!
../iup/vo.cpp:312
Expression: _i != s_wndlookup->end()

Report this via bug submission as well....

Posting the solution here for the next person. Turn out it's something odd with plugins that use the iup.Matrix.

After the dialog that contains the matrix is delcared, you need to call the map() function of the dialog.

So:

dlg = iup.dialog{ ..definition here.. }
dlg:map()

Thanks to Mick, who set me straight!
