What happened?

Linux generic uninstaller silently fails to update-mime-database.

This issue also affects 7.0.14.

When running the Makeself script with the uninstall argument, the process was supposedly successful, but shortly followed by a desktop crash. Not even my display manager survived (I use LightDM with the GTK greeter).

Thorough investigation revealed that GTK failed to draw any pixbufs because its MIME is unknown or something like it.

update-mime-database /usr/share/mime fixes the problem.*

Given that the above is already in the uninstall script, I suspect that it failed there but was suppressed > /dev/null 2>&1. Thus we never know that it failed and why.

Since there are no fallbacks, I suggest to investigate why update-mime-database fails on the script.

*on a spare TTY (e.g. Ctrl + Alt + F1): login, then run said command as root.

How can we reproduce this?

On any GTK-bound desktop environment and with VirtualBox installed with the Makeself script, run said script with the uninstall argument.
