Extension Manager fails and so do certain scheduled jobs
I was able to reproduce your issue and fix it on my Linux install.


It seems to only happen with Linux, not MacOSX.
I can fix it by changing the filename of the job to be first letter caps only, i.e. not camel case. Don't make any other changes.


Following the advice in various other locations, including civix or related issues, does not fix it (shortening, changing to all lower case, etc.).

I think part of the noise of this issue is related to changes in the upcoming v4 api which are not true of the v3 api that were introduced in 4.6.

My suspicion is that this patch is responsible for breaking things:
