#536 closed defect (fixed)

Showing the screenshot

Reported by: anonymous Owned by: Radek Bartoň
Priority: normal Component: ScreenshotsPlugin
Severity: normal Keywords:
Cc: jgodoy@… Trac Release: 0.9


After installing the component, upgrading, etc. I've added a test screenshot to see how it works. Just after the insertion, there's no "preview" and if I click on the red rectangle I get the following error page:

Trac detected an internal error:

content_type must be a string

If you think this really should work and you can reproduce it. Then you should consider to report this problem to the Trac team.

Go to and create a new ticket where you describe the problem, how to reproduce it. Don't forget to include the python traceback found below.

Any hints on what I might be missing? This is with installed.

Oops. I forgot mention that imagemagick tools is needed for generating previews. I'll fix it right now.
