Steps to replicate the issue (include links if applicable):

• Go to https://commons.wikimedia.org/wiki/File:57_G_Tumkur_(1929).jpg
• Click on Georeferences the map in Wikimaps Warper

What happens?:

• Fails with a log error: "We're sorry, but something went wrong."

More specifically, I have found that any maps added to Wikimedia Commons should be given about a day for Commons to work on the images before Attempting addition to the Wikimaps Warper. Uploading a map to Commons and immediately attempting to add it to Warper leads to such errors. Perhaps it can check for this precondition of Commons running imagemagick etc. and avoiding this situation should be considered.

What should have happened instead?:
Assuming my reasoning is right - If the map is being attempted to be added too soon, the Wikimaps system should detect perhaps the timestamp and just say Wait for 24 hours before attempting to add.
