EasyTimelinePlugin not working on 1.1.3 foswiki

Extension is installed and enabled. Path to ploticus is set to /usr/bin/ploticus and path to script is set to /var/lib/foswiki/tools/EasyTimeline.pl. But the plugin does not work.

The debug is enabled:

2011-09-12T12:43:17Z debug - EasyTimelinePlugin::commonTagsHandler( (Missing or illegal web).WebPreferences )
2011-09-12T12:43:17Z debug - EasyTimelinePlugin::commonTagsHandler( (Missing or illegal web).WebPreferences )

apache error log:
... view: Use of uninitialized value in concatenation (.) or string at /var/lib/foswiki/lib/Foswiki/Plugins/TimelinePlugin.pm line 84., referer: http://.../System/EasyTimelinePlugin

What is the problem?

Do you have the required dependencies installed?

I get a different bug than your's. First I had to make the working dir writable by the webserver. Now it saves an image file in working/work_areas/EasyTimelinePlugin/tmp but the saved file does not have the extension png. Foswikitask:Item11130

My Problem was that TimelinePlugin was also installed and enabled. After disabling it, EasyTimelinePlugin works as it should.

This plugin is actually busting up all of the Foswiki engine while tinkering with the umask(). Changing the umask has got fatal side effects for the rest of the engine: it then creates files not readable by itself.
