I did that test, the same bug occurs.
I may have not been clear enough in my description. By "hovering over a tab" I meant
that the mouse cursor points at one of the filenames listed in the tab "headers".
I did not mean the input editing area.

I added that to /etc/apt/sources.list and installed the pluma-dbgsym
package, then created a new user. I observed the same bug again.
In my original user I have the following plugins enabled:
Change Case
Document Statistics
File Browser Pane
Insert Date/Time
Modelines
Sort
Spell Checker
Tag list
Disabled plugins in my original user:
Save Without Trailing Spaces
In the new user, I have the following plugins enabled:
Document Statistics
File Browser Pane
Insert Date/Time
Modelines
Spell Checker
And the disabled plugins in the new user:
Change Case
Save Without Trailing Spaces
Sort
Tag list
I also tried as the new user with all plugins disabled, still same bug.
Here's the backtrace (as the new user, listed plugins enabled):
