What is the *exact* error message?

The exaxt error message (it's german):
Leider ist ein Problem aufgetreten.

Ein Problem ist aufgetreten, welches vom System nicht behoben werden kann. Bitte melden Sie sich ab und versuchen Sie es erneut.

Did you mean that?

Yes, though no idea which module that one comes from...

I have the exact same problem. I'm sorry but no additional error message (except mine is in French).

Ok the error is a standard fail whale, I suppose.

You need to grab .xsession-errors instead. But it is very likely that it is a known bug: xrandr-indicator requires a gjs patched for bug 634253

Crash when using xrandr-indicator

Giovanni is right. This is linked to gjs "Only supporting null-terminated arrays of strings"

This was fixed with bfd107cef010418ee8439b222e94128cfe7c3dd2 (require gjs version)

This problem has been fixed in the development version. The fix will be available in the next major software release. Thank you for your bug report.
