Segfault when launching Xviewer

[poldon]

 * Xviewer version (xviewer --version): Xviewer 2.8.3
 * Distribution - (Mint 17.2, Arch, Fedora 25, etc...): Mint 20.1

Issue Xviewer logs several errors to the console and then segfaults when launching. If I reboot, the issue goes away. This happens quite often on my machine.

Steps to reproduce

1. Launch Xviewer. This happens whether I launch from the shell or from Nemo.

Expected behaviour Xviewer should launch cleanly.

My comment to your issue #141 applies here - disable the display EXIF plug-in and you will get rid of at least some of the error console messages. Given that parts of the EXIF plug-in seem to be missing you will lose nothing. I suppose there is a possibility it will stop the segfaults occurring.

did that help? @poldon

I had rebooted after reporting this, and it has worked fine since. Not sure why, but I'll close this.
