Error `mime parse error: a slash (/) was missing between the type and subtype` on every command

[jakobhellermann]

I'm getting this error whatever I do.

~ λhandlr list
2025-08-29T17:23:18.078333Z ERROR handlr::error: Custom("mime parse error: a slash (/) was missing between the type and subtype")
 ~ λ handlr get .png
2025-08-29T17:23:20.398746Z ERROR handlr::error: Custom("mime parse error: a slash (/) was missing between the type and subtype")

I haven't looked into why this happens yet.

Looks like I had

[Default Applications]
gale=gale-handler.desktop

from https://github.com/Kesomannen/gale

Presumably due to these lines:
https://github.com/Kesomannen/gale/blob/2309a1bc02e2d5a5c1c67817450849424c7b3ce0/src-tauri/tauri.conf.json#L57-L58

I could just remove those for now but some ideas

• maybe gale should be using different (valid?) mime types
• it would be nice if the error message was a bit more descriptive. Even mentioning .config/mimeapps.list would help
• maybe the crate should parse more resiliently here? I don't know how common this issue is

This might be from an old version of tauri, I removed the entries and reinstalled gale and it only added x-scheme-handler/gale.

Sorry for taking a while to get to this.

It seems like it was an issue with gale or tauri, not handlr-regex.

However, you do have a good point about improving the error message and the parsing should be more resilient so that a single invalid mimetype in mimeapps.list does not cause everything to break like this.

Ran into the same issue with hopscotch, even though I uninstalled it months ago. Removing it from mimeapps.list fixed it.
