KeyError: 'tracsubtickets/htdocs'

[white-space]

I like this plugin but it seems to interfere with other plugins.

Using trac 0.12 with TracSubTicketsPlugin 0.1.0 makes TracTags 0.6 output look like without CSS rendered and TracWysiwyg 0.12.0.2 toggle switch is like removed.

This is a snippet from trac.log:

I also love this plugin but have the same issue but in my case it's with the TracWysiwygPlugin.
Its radio buttons won't appear when this plugin is enabled.
If I first disable and then enable this plugin it will work for a while, haven't quite figured out when it stops working, but it seems that when I have a session running while the this plugin is disabled and then enabled it will work. When I start a new session it stops...
Seems that something is cached in the session.
I essentially get the same output in trace.log as white-space.

I'm using trac 0.12, tracsubticketsplugin 0.1.0 and tracwysiwyg 0.12.0.2.

This can be solved by creating an empty directory "htdocs" within the .egg, for example:
unzip TracSubTicketsPlugin-0.1.0-py2.5.egg
mkdir tracsubtickets/htdocs
zip -r TracSubTicketsPlugin-0.1.0-py2.5.egg tracsubtickets

Hi. I tried the above recommendation, but got the following error listed at the end of this comment. I have given full access to the user, and have even tried granting write access to user, group and other, but it still can't extract the egg after adding the htdocs directory.

I'm afraid I'm a novice at apache/python. Any recommendations would be greatly appreciated.

cache:

  [Errno 21] Is a directory

The Python egg cache directory is currently set to:

  /usr/tracconfig/eggs

Perhaps your account does not have write access to this directory?  You can
change the cache directory by setting the PYTHON_EGG_CACHE environment
variable to point to an accessible directory.

I was able to solve this issue by creating a new dir /htdocs/css/ under the following build directory (/build/lib/tracsubtickets/). I then added this file to the dir:
https://github.com/tonin/trac-subtickets-plugin/blob/master/tracsubtickets/htdocs/css/subtickets.css

Finally, I rebuilt the egg file and that solved the issue.

Confirming both bug and solution.

I'm not sure that the initial WysiwygPlugin issues are related to the issues reported near the end of this ticket, however to address the latter issues, I wonder if someone could described how they created and installed the egg, so that I can try to reproduce. I haven't had any luck reproducing the issue so far.
