The same error occurs with .tif files. It's not a filesize problem : here is the error produced when lauching Hugin in a terminal :

Pictures produced by Gimp 2.8 are exported from standard Gimp working format (.xcf) to either png or tif format with standard options.

I noticed that they both have 2 channels : grey and alpha channel, and the same picture in jpg format as only a grey channel, no alpha.

The final picture produce by Hugin with the jpg picture is in .tif format and has 2 channels (grey and alpha) when opened in Gimp.

So I don't really understand the problem, but I'd like to work with a non destructive file format, no jpeg
