Hello, this really looks like a concurreny problem on the font subsetting 
feature.
The subsetted file is written in the fonts directory with a pattern like this : 

[original font name].tmp.[CRC32 of the subset]

But, if more than one document with the same character set are generated at the 
same time, they use the same file, locked by one of the processes.

I'll change it to take a random name.
