Bug#898637: Pluma text editor crashes when scrolling while hovering over a tab

["C. Masloch" <pushbx@38.de>]

Package: pluma
Version: 1.20.1-2

The MATE desktop environment visual editor Pluma crashes whenever I
scroll (press either the mousewheel up or down button) while the mouse
cursor is hovering over one of Pluma's tabs. It doesn't seem to matter
how many tabs are open. If I start Pluma from a terminal window, the
following error message is shown then:

$ pluma
Segmentation fault
$


I'm using buster, with the following kernel and libc:


$ uname -a
Linux [hostname] 4.15.0-2-686-pae #1 SMP Debian 4.15.11-1 (2018-03-20)
i686 GNU/Linux
$ apt show libc6 | grep ^Version

WARNING: apt does not have a stable CLI interface. Use with caution in
scripts.
