My recommendation is to install cmake, git, build-essential, and xorg-dev, and then check out v.2.3.9-ah
Code:
git clone -b v2.3.9-ah https://gitlab.com/tome2/tome2.git
and compile
Code:
cd tome2
cmake .
nice make
Alternatively, if you want to stick with 2.3.5, you could install gdb and try to pinpoint the issue.
Code:
gdb /usr/bin/tome2
run -mx11
And then when you get a crash
Code:
bt
will get you a stack trace, showing which function it crashed in.
Good luck!
P.S. I bet this is Ubuntu's buffer overflow detection.
Edit: actually let me try to reproduce this...
