mate-terminal sometimes crashes with segfault in libgtk-3 when right-clicked

Postby Emerson Prado » Fri May 26, 2017 3:07 pm

Hi all,

I observed some crashes in mate-terminal, and they are not consistent. Until I can tell what triggers the problem, I'll blame bad luck on it.
The crashes usually occur when I select text in the terminal screen, then right-click into the terminal right away to copy such text. It seems to depend on some combination of mouse events.

This is what I got from /var/log/messages:

Code: Select all

kernel: [791449.651328] mate-terminal[26369]: segfault at db ip 00007f06b2084ec6 sp 00007fff53b066d0 error 4 in libgtk-3.so.0.1400.5[7f06b1d65000+6a5000]


About the related application and library:

Did anyone see anything alike? Any hints? I think about filing a bug, but would like to grab more data.

Best regards,

At first I thought it was this bug, which was fixed in mate-terminal 1.18.1.
But I realized you already have that version...

I'm trying to reproduce it in Betsy but no luck yet. I'm running it in a VM, maybe that matters.

I think it's important to highlight that, unlike the bug reports, my X server doesn't crash. Only mate-terminal.

It happened again today, and I'm puzzled to notice that the error message (in /var/log/messages) points to a different library:

Code: Select all

Aug 11 12:27:20 <Host> kernel: [ 1378.950705] mate-terminal[1879]: segfault at b2a ip 00007f0307679fef sp 00007ffdc076ecc0 error 4 in libgobject-2.0.so.0.4200.1[7f0307647000+51000]


There must be some specific condition for the crash. The only thing I can think of is a fast mouse stroke which combines to something else, like hitting another button, moving, etc. But it's only a guess.

Thanks,
Emerson
