Bug#861575: tilix: Does not start on Stretch (symbol lookup error: undefined symbol)

[Mathieu Basille]

Package: tilix
Version: 1.5.4-1
Severity: grave
Justification: renders package unusable

Dear Maintainer,

Following the name change from terminix to tilix, I updated 
my Stretch system (which uses apt pining to install Sid 
packages whenever possible) to use the new developments of 
tilix.

Install of v1.5.4-1 works without any problem, but I'm unable
to run tilix:

tilix: symbol lookup error: tilix: undefined symbol:
 _D7gobject7ObjectG7ObjectG11addOnNotifyMFDFC7gobject9ParamSpec9ParamSpecC7gobject7ObjectG7ObjectGZvAyaE4gtkc12gobjecttypes13GConnectFlagsZm

I am not sure where to start from here to debug it in more 
details. Maybe that's just expected in trying to install it 
on Stretch.

However, and that's the tricky part, I tried to revert to 
terminix (which is still available as v1.3.0-5 in Stretch), 
and the install now fails with:

The following packages have unmet dependencies:
 terminix : Depends: terminix-common (= 1.3.0-5) but it is
 not going to be installed
E: Unable to correct problems, you have held broken packages.

All in all, I'm now unable to have any of terminix/tilix. Any
suggestion would be greatly appreciated.
Mathieu.
