No icon showing on Linux Panel ... Silly issue but...

[GitHubbet]

Hi
Noticed on Linux Mint 22.3 when I run Qjackctl or it runs at startup, its icon is white with [!] - no Qjackctl icon appearing.

How to fix?

I do mean the one that the application itself makes appear on right side - where all standard controls are, not the added (or not) Qjackctl app icon).

See image:

Thanks

PS maybe file permissions? If so, how to fix? Thanks

not sure but this might be due to qtsvg package is missing somehow
