Log 5.0-rc3 with +seh

Up to version 5.0~rc2 the autocomplete feature worked fine in SharpDevelop 5.1.
> From 5.0~rc3 it's difficult to write something since when the popup from the

autocomplete is shown, the focus from the textbox seems to be stolen so you
need to click back into the textbox to be able to type again.

SharpDevelop 5.1 download:
https://sourceforge.net/projects/sharpdevelop/files/SharpDevelop%205.x/5.1/
SharpDevelop requires: dotnet40 or higher and vcrun2008

Working with: 4.21-staging 5.0~rc1-staging 5.0~rc2-staging
Not working with: 5.0~rc3-staging 5.0~rc4-staging 5.0~rc5-staging

OS: Ubuntu 18.04.3
Log is attached with WINEDEBUG=+seh , the last 45 lines are printed when typing
a character and the autocomplete popup opens.

Plain wine currently crashes when typing but it worked before on 4.21 so I
currently can't check with plain wine.
