Application crash on WSL in the mounted disks screen

[cheatsnake]

I installed gdu on Ubuntu 22.04 in WSL and running application with -d flag (which stands for mounted disks), then I choose the root directory of my disrto (/mnt/wslg/distro) and got panic error:

user@localhost:~$ gdu -d
panic: interface conversion: interface {} is nil, not *device.Device [recovered]
        panic: interface conversion: interface {} is nil, not *device.Device

More interesting that after repeating this proccess again everything surprusely worked, but after sometime the error occurs again. It looks strange, so maybe this issue will be helpfull.

What is the version? Mine is 5.21.0-1+b2 and does not give the error

What is the version? Mine is 5.21.0-1+b2 and does not give the error

$ uname -r; lsb_release -a
5.15.90.1-microsoft-standard-WSL2
No LSB modules are available.
Distributor ID: Ubuntu
Description:    Ubuntu 22.04.2 LTS
Release:        22.04
Codename:       jammy

And now I also no longer have the error. Probably this can only happen at first runs...

[daniejstriata]

OK. What is the version of gdu though?
