guake package does not tag python3-gi-cairo as a dependency

[David Lee]

upon getting Guake running after working around bug 1853698, I noticed that Guake did not respond to the keypress to hide/show and was printing this error to console at a rate of one line a second while the console is shown:

TypeError: Couldn't find foreign struct converter for 'cairo.Context'

Upon further googling, I found the hint to a workaround in https://github.com/rbgirshick/py-faster-rcnn/issues/221

where the package that is actually needed by guake is actually python3-gi-cairo and not the python2 version mentioned in that article. Installing this package made guake respond to the keypress for hide/show and stop printing the error.

Again, I think this is a package metadata problem, like gir1.2-wnck-3.0, python3-gi-cairo should be entered as a dependency of the guake package.

I uninstalled python3-gi-cairo on Ubuntu 19.10 and that cause the same issue as David Lee mentioned.

apt-cache depends guake indeed does not list python3-gi-cairo as dependency

I forwarded the bug to Debian - I will add link to the upstream bug as soon as I receive email for it
