[blocker] Missing filename extension

[vitaly-zdanevich]

This is a serious problem, and maybe because of that - after uploading - Darktable crashes for me.

On the first line of register_storage_store I added print(tmp_exp_path) and got /tmp/1452 Бобруйск, ул Чонгарская 55.()

dtMediaWiki/dtMediaWiki.lua

Line 384 in d1822b5

local function register_storage_store(_, image, _, tmp_exp_path, _, _, _, extra_data)

I "fixed" it locally by hardcoding

dtMediaWiki/dtMediaWiki.lua

Line 369 in d1822b5

local extension = fn:match("[^.]+$"):lower()

to local extension = "jpg"

We already had a discussion about the issue. It looks like it works on your machine, but not on mine?

I created the issue on Darktable darktable-org/darktable#18817
