Hi!

First of all thanks to all people working on this port and keeping qt libra=
ries
up to date.

Unluckily, after the update to qt 6.6.0 in ports commit
1d76bdf62dffad91834699701f41d3374dfb6a3a the qt6 flavor of telegram desktop
fails to start.

I don't have debug enabled binaries available, and have not investigated mu=
sh,
but I got this using lldb:

```
(lldb) run
Process 4360 launched: '/usr/local/bin/telegram-desktop' (x86_64)

(lldb)=20
```

Looks like this affects linux too and has already been reported upstream:

The issue could be in qt6svg but I was unable to find a bug report about th=
is
in qt6 bug reporting system.
