#bugreport: when tapping on an attachment in #arcanechat and #deltachat, it asks me what app to open with, but it never works.

if i open this pdf with pdf reader, it opens an empty "null.pdf".

if i "save as ..." with #materialfiles, it throws an error, see screenshot.

however, long-pressing the message and "export attachment" works just fine.

i report the issue here because i recently deleted my #gitslop account. ✨💩
