Crashes on Nextcloud 2.5.2's AppImage as well.

[azubieta]

This error is from the 0.1 versions of libappimage. Would you please verify which commit is actually being used?

@probonopd would you please provide a link to the offender Firefox AppImage?

@TheAssassin I wasn't able to reproduce the Nextcloud 2.5.2 AppImage issue using libappimage v0.1.x-legacy on Neon.

[TheAssassin]

@azubieta as I wrote in TheAssassin/AppImageLauncher#127 (comment), the error goes away when AIL is built on the test system. I also have no idea what could cause this, my best guess is that it's due to some GLib ABI differences or so.

[probonopd]

Why not use the glib function to get the keys rather than doing it low-level?

[azubieta]

@probonopd in v0.1.x we do use glib functions to get the desktop entry keys. Or you mean other keys?

[probonopd]

@TheAssassin before I mix up our findings from yesterday, I let you explain (regarding counting the localized keys)

[TheAssassin]

@probonopd that's not guaranteed to be the root issue any more from my investigations.

The same AppImage with the same AppImageLauncher does NOT crash on xubuntu-19.04-desktop-amd64.iso:

me@host:~$ AppImageLauncher --appimagelauncher-version
AppImageLauncher version 1.2.2 (git commit 9aedcf2), built on 2019-05-24 14:45:41 UTC

Is it random or do we see a pattern?
