paste method freezes autokey-gtk in Ubuntu 14.04

[Rob]

In a fresh install of Ubuntu 14.04.2 LTS, the autokey-gtk application (0.94.1-4) crashes when the paste method is used. This causes keyboard input to freeze in the application where the autokey was used, and if typed again, in all applications. Here is the debug output from using the autokey twice in gedit (the traceback is after the first time, and autokey-gtk was killed after the second time to get input back in all applications):

Patch to resolve the issue in Ubuntu 14.04.2 LTS is attached, but there may be more places where set_text() is not passed the appropriate number of arguments:

$ grep -Hrn "set_text(" /usr/lib/python2.7/dist-packages/autokey/ | wc -l

[Thomas (tux12345)]

The »TypeError: set_text() takes exactly 3 arguments (2 given)«
was caused by a GTK2 to GTK3 port and is fixed for the general case in
https://github.com/autokey/autokey/commit/572316bd17f4c45dc38ca149962ca176865a2f2a and fully in
https://github.com/autokey/autokey/commit/d6efe4edfb81eeb2300f8a67f210d845a56188f9
This bug triggered another bug (https://github.com/autokey/autokey/issues/72) in broken X11 keyboard grabbing logic (symptom: keyboard input lock), which is fixed in
https://github.com/autokey/autokey/commit/0afdb9770f614ecb9f848b03b180d537cfe975bc

Those commits are part of version 0.95.1, resolving this issue when Ubuntu packages version >= 0.95.1.

[Thomas (tux12345)]

This issue is fixed in 0.95.9, which is part of Ubuntu 20.04
