--- Comment #4 from Vincent Povirk madewokherd@gmail.com 2012-11-26 09:15:19 CST --- I saw a similar-looking error in another program that was caused by an incomplete implementation of the Microsoft.VisualBasic.ApplicationServices.WindowsFormsApplicationBase class. That class has other events, including a Startup event that should be called before OnRun, that are never raised by the open-source version of the VB.NET class libraries. This causes the program to not initialize some variables, leading to a null reference exception when it tries to use them. This needs tests and a fix to be submitted to the mono-basic project.
It could also be some other bug. One could verify that by hacking the WindowsFormsApplicationBase class, assuming the Startup code actually works.
I think this bug would be a good starting point for someone wanting to get into wine-mono development (and we desperately need more people doing that).
