** Description changed:
+ [Impact]
+
Signal handlers for the "switch-page" signal are continuously being
registered when a new tab is opened and are not correctly cleaned up
when a tab is closed causing a linear increase in invoked callbacks when
a user switches tabs.
Affects Version: 1.5.0-1.1
Fixed Version: 1.5.2-1
The fix is already in Debian unstable and also in Ubuntu Groovy but
requires an SRU upload for Focal.
Relevant upstream bug:
https://github.com/lanoxx/tilda/issues/421
[Test Case]
- 1. This can only be observed in the debug mode when the invocation of the
signal handler callback is logged to the console. In debug mode users would see
the "tilda_terminal_switch_page_cb" message to be printed N times for N tabs
that have been opened (for the life time of the process including for tabs that
have already been closed).

Expected result: the switch-page callback is invoked exactly one when
the user switches between one tab and another one.
The fix is part of tilda 1.5.1, see upstream milestone for 1.5.1 which tracks
the corresponding issue #406:
https://github.com/lanoxx/tilda/milestone/7?closed=1
+
+ [Regression Potential]
+
+ The regression potential for the switch-tab signal handler change is
+ minimal, the code itself has not changed, the signal is just registered
+ to a different object to avoid registering it multiple times.
