/usr/bin/muon-discover:6:__GI_raise:__GI_abort:qt_message_output:qt_message:qFatal

[errors.ubuntu.com bug bridge]

[Impact]

the new sourcelist api in qapt forgets to do a size check after string editing, thus running into an assert on qstring::at(0) being called on an empty string.
this was resolved by making sure that the value passed to at() is actually a valid index.

[Test Case]

* edit /etc/apt/sources.list
* add a line consisting of two hash signs "##"
* save
* start muon-discover
* click sources tab at the top
* should not crash

[Regression Potential]

N/A. SourceEntry tests continue to pass, new test was added.

[Other Info]
