I installed gedit-latex-plugin in Ubuntu Vivid via aptitude without errors. Trying to activate the plugin in gedit via Preferences > Plugins results in a runtime error and the plugin not getting activated.

Any hints on how to tackle this would be very much appreciated.

The full error output is like follows:

And in the GUI it looks like this:

gedit Latex plugin not getting activated

  • I just installed this package in Ubuntu 15.04 64 bit and it is working correctly. Could you try to re-install: sudo apt-get install --reinstall gedit-latex-plugin ? – Luís de Sousa Jun 1 '15 at 12:21
  • Thanks for your reply, Luís. I did the reinstall but it still fails activating. – anothernode Jun 2 '15 at 12:59
  • I also reinstalled the packages dbus and dbus-x11 as the python stack trace points to some error related to dbus. But I don't really understand at all what is going on in that add_to_connection function in service.py. It seems as if there is some kind of problem connecting to the dbus service. – anothernode Jun 2 '15 at 13:44

This error has been reported in previous Ubuntu versions. This plug-in works perfectly on a fresh system, but happens to fail on systems resulting from release upgrades.

Since this is Python (an interpreted language) it is possible to comment out the offending instruction where D-Bus is invoked. Open the Python script with your favourite text editor:

sudo gedit /usr/lib/gedit/plugins/latex/job.py 

Then comment out line 160, i.e., add an hash character in front; it should look like this:

# dbus.service.Object.__init__(self, bus_name, OBJECT_PATH)

GEdit should immediately portrait this line in a different colour. So far no secondary consequences have been reported with this instruction commented out.

Then restart GEdit and try again to activate the plug-in.

  • The plugin works in Ubuntu 15.04, also without comment out this line. Have you tested the solution? – A.B. Jun 3 '15 at 15:16
  • Thanks again, Luís! I am able to activate the latex plugin after commenting out line 160 in job.py. My Ubuntu 15.04 was a fresh install, not an upgraded system. It would still be great to find out why something and what exactly is going wrong with dbus. I recently deleted ~/.dbus because I assmued it is only temporary data that gets recreated anyway. Now I see that I still have no .dbus directory in my home even after a restart. I wonder if there might something generally going wrong with dbus on my system. – anothernode Jun 3 '15 at 16:04
  • I have a ~/.dbus folder, but I doubt it is related to the error you are getting. I suspect more of some particular Python package modifying the usage of D-Bus. If you want to get to the bottom of this you might open a bug at launchpad or at GNome's Bugzilla. – Luís de Sousa Jun 4 '15 at 7:17
