Fatal IO error 11 (Resource temporarily unavailable) on X server :0.0

Versions

  • OS: xUbuntu 18.10 with updates as of 2018-11-18
  • Gajim version: 1.1.0-2 (from official PPA / ftp.gajim.org)
  • GTK version: 2.24.32-3ubuntu1 and 3.24.1-1ubuntu2
  • Python-nbxmpp version: 0.6.8-1

Steps to reproduce the problem

  1. Start Gajim
  2. Open a chat window with HTTP uploaded image with long filename in history
  3. Watch Gajim crashing

Expected behavior

Gajim keeps running, maybe shows an error popup.

Actual behavior

Gajim crashes completely with "Fatal IO error 11 (Resource temporarily unavailable)". (Previous version 1.1.0-beta2 of Gajim gave "BadImplementation (server does not implement operation)".)

It seems to be caused by a HTTP uploaded image with a very long filename.

The URL of the image it tries to show is something like https://xmpp.myserver.com/upload/7cdbe36276846214d3ea1062732aa5b1e47f164d/VfqaZYeJ3CSz4JHDnkAhdgZRE7cqKfZHY1RPGNSO/2018-11-19_17_31_41-Neue_Nachricht___Geben_Sie_den_Devs_ihr_Ops.__-_my1234_email.com_-_Email_-_Vival.png.

I don't know if this is something the Url image preview plugin should catch. However, I think a plugin error shouldn't be able to completely crash Gajim.
