tuxmath crashes when playing factoroids

[Gabriel Gourichon]

Hello,

# Context

Playing the "factoroids" part of tuxmath.

# Expected

Ability to complete full stages and move on (it sometimes happens).

# Observed

After one or several minutes, game crashes : window disappears.
If launched from terminal, the message below appears:

"Erreur de segmentation (core dumped)"

# Additional information

Reproducible: always, after a variable play time. Sometimes the game runs long enough for the player to reach second stage "multiples of 3".

Running under gdb shows this:

Program received signal SIGSEGV, Segmentation fault.

I can reproduce this error in trusty, especially if firing in rapid succession
