Document Viewer Crashes Knime - Logs attached

Hello, this is more of a bug report but it would be nice to receive a solution if you figure it out. I installed Knime 2.12 some time ago and had a workflow where this Document Viewer worked fine. Now, the same Document Viewer crashes Knime (it just closes instantly with no warning and whatever state I was in is not saved) when I click on one of the documents to view it . FYI...

Hi,

thank you for reporting this problem. This is a Linux gtk issue and can be avoided by adding the following two lines to the knime.ini before the vmargs.

--launcher.GTK_version
2

It is important that the two lines are before the vmargs and that thw value 2 is in a separate line.

Cheers, Kilian
