Bug#920813: sooperlooper does not show GUI

[alberto]

Package: sooperlooper
Version: 1.7.3~dfsg0-3+b1
Severity: important

Dear Maintainer,

I wanted to use sooperlooper in my debian/sid (already tested in
ubuntu studio) and IU faced this problem:
sooperloper starts (I can see read/write clients in jack connection, but no
GUI  is displayed.

If started from terminal, I got the following message (doesn't seem to contain any error or warning):
