[Eric] Some eric4 issues

[Hans-Peter Jansen]

Dear Detlev,

I'm glad, you fixed the pysvn issue for eric4 not finding any source files 
anymore. Thanks. Meanwhile, I switched to the svn module, and noticed, that 
the files colorization depending on state doesn't work anymore for it. 

BTW, I reported a bug that leads to segfaults on exit for eric4, which you 
couldn't reproduce. Here's a recipe, that's perfectly reproducible for me:

Start eric4, load a project with a few python files, and use that split 
view context menu option (Neue Ansicht (in neuem Abschnitt)).

Close eric4. Bang. Backtraced below. This is 100% reliable for me. 
(openSUSE 13.1/x86_64), eric 4.5.17 (from home:frispete:PyQt).

I guess, that splitting the view adds some object to the menu, which is not 
properly destructed on close..

Let me know, if it is reproducible for you too, now.

Cheers,
Pete
