Sorry we crashed while openning an assembly

[greenozon]

Steps to reproduce

1. Try to open up assembly (it's protected, yes, but crash is not expected, just error message!)

Error message shown

System.BadImageFormatException: Row ID or heap offset is too large.

Expectations: show only text error, remove strange mesage box

Did you forget to attach the assembly?

[greenozon]

yeah, sorry

password-protected rar?

[greenozon]

pardon me, my mistake
link fixed (above)

[siegfriedpammer]

The assembly is completely broken, even after somewhat gracefully handling the invalid handles into the String heap, ILSpy is unable to decode/show any method body, because the method body headers are invalid. What would you expect us to do?

[greenozon]

just dont show the "we crashed" dialog, it is very scary
the error text on the right pane is enough! :)

PS hte assembly is still workable and runnable
