Parole crashes when choosing to open a file if MPRIS2 plugin is deactivated

[Leonardo Müller]

Hello

I have noticed that, if the MPRIS2 plugin is deactivated and I choose the option to open a file, parole will crash with a segmentation fault.

On dmesg the following message appears:

[ 1360.591587] parole[6684]: segfault at 2d ip 000055f120077cba sp 00007ffc032c88c8 error 6 in parole[55f12004c000+5b000]

OS: Xubuntu 17.04 amd64
Parole version: 0.9.1-0ubuntu1

Expected behavior: the window to open a file would appear and I would be able to choose a file;

Observed behavior: the borders of the open file window appear, then parole crashes.

I am unable to reproduce this with the latest release (1.0.1). Can you attempt to reproduce this bug?

I'm using now Xubuntu version 18.04 that has parole version 1.0.1 and its still happening. Using gdb, it shows the following backtrace when it crashes:
