Version: (using KDE 4.0.1) Installed from: Ubuntu Packages OS: Linux Binary package hint: kgraphviewer-kde4 When I tried to run a cluster example from graphviz.org website, kgraph comes up with a blank screen. Doesn't show any errors whatsoever. I recently updated ubuntu gutsy gibbon to hardy heron 8.04 using update manager.
Could you attach the file causing the problem or give the URL to it, please ?
The file can be found at http://www.graphviz.org/Gallery/directed/cluster.html. Actually I tried to load different types of dot files, but it always came up with a blank screen. Thank you.
Could you give the versions of kgraphviewer and of dot, please ? Could you also give me the names of the kgraphviewer and GraphViz packages that are installed ? Thanks
Sorry,but could you also detail how you create/download the dot files and how you load them ? It's to be sure that you don't try to load the SVG file or another unsupported format. In this case, it would silently failed, except for the console indicating kgraphviewer(2302): parsing failed
1) Graphviz version 2.16 (Fri Feb 8 12:52:03 UTC 2008), KgraphViewer version 2.0 (using KDE 4.0.3) ( I am not sure wht do u mean my names of kgraph and graphviz) 2) I just downloaded the example from the website and copied into a plain text with dot extension. Dot was able to interpret it and convert into a PNG file.
I compiled graphviz 2.16 and kgraphviewer from trunk still works for me. So, it seems it's not a graphviz related problem. I wanted to know the exact name of the binary packages (like kgraphviewer-kde4.deb for example) in order to be able to try it or ask someone else to try it. Could you send me one (or attach) of the dot files you created ? The way you do it seems OK but I'd like to be sure. You could also try to load one of the file given with graphviz. On Mandriva, it's for example /usr/share/graphviz/graphs/directed/clust.dot Finally, could you run kgraphviewer in a terminal and send me the full debug output (to be sure it is active, you can choose "Select all" in kdebugdialog)? Thanks for your help

I installed Kgraphviewer right from the svn repository (svn co http://svn.gna.org/svn/kgraphviewer/trunk kgraphviewer). The dot file and the debug output files are attached.Also I updated the graphviz version to 2.18, but the problem still persists.
Created attachment 24369 [details] trace of kgraph error
I installed latest version of ubuntu (hardy heron), but kgraphviewer still display a plain blank screen. The package is included as part of the ubuntu OS. I feel inclusion of certain non-working packages without sufficient testing certainly doesn't attract much users for ubuntu. Kleag, can you please apply a patch and upload it as one of the ubuntu updates. As a ubuntu user and a fan of open source community, I express my deep concern.

I confirmed the bug by using a Ubuntu Live CD. I'll try to correct it during my holidays, starting on thursday. I'll install an Ubuntu somewhere. I suppose it is a library problem. I'll check if there was problems with QGV in the Qt version used.

Actually I came across your package in graphviz resources section and was attracted by some unique features in kgraphviewer, which I really want to try out. Your decision to make it as an open source package is very much appreciated.
