Description Sophie Hirn 2019-01-01 15:48:36 UTC 
xdg-open can be brought to recurse endlessly into a crash with the following setup:

1. Inside the search path for .desktop files, place a directory with name (e.g.) `Grinding Gear Games`

2. Create a directory named `Games` in your home directory.

3. Create a subdirectory named `Grinding Gear Games` somewhere inside the `~/Games` directory.

Now, running e.g. `xdg-open https://en.wikipedia.org` from your home directory will result in an endless recursion and inevitable crash.

I've already found the offending line, it's `scripts/xdg-open.in:330`, which reads `for d in $dir/*/; do`.

The spaces in the directory name mentioned above lead the search into `~/Games` due to improper space handling, and the directory `~/Games/<...>/Grinding Gear Games` makes the search go back to `~/Games` again.

However, I haven't found a POSIX-compliant way of fixing the problem without restructuring the entire function yet, all my attempts relied either on bash-specific behaviour or GNU extensions to `find`.
