Created attachment 80321 [details] Massif file which makes it crash
Confirmed a while ago, I think someone reported that on the ML or in a private email. The issue is actually in KGraphViewer which simply does not work at all anymore with a somewhat recent update to the GraphViz library... I could not find a solution for it when I looked the last time. If you could take a look and figure out whats going on that would be cool!
Since kgraphviewer in git was updated to work against latest graphviz, could someone retest against that? Note that this looks like another case of both new and old versions of the graphviz libraries being loaded, so programs will "randomly" execute (incompatible) functions from the one or the other since they have the same name. graphviz could have avoided these issues e.g. by proper use of symbol versioning.
Awesome, it works again - thanks!
