Bug#1108991: pavucontrol fails to launch withh error while failing to load shared object

[Manoj Srivastava]

Package: pavucontrol
Version: 6.1-1
Severity: important

This is on Trixie RC2, current as of July 8th, 2025.

Couldn't open libGLESv2.so.2: libGLESv2.so.2: cannot open shared object
file: No such file or directory
[1]    139148 IOT instruction  pavucontrol
---------------------------------------------------

I recompiled on this machine (apt-get build-dep pavucontrol; cd
pavucontrol-6.1; fakeroot ./debian/rules binary), but the results were
unchanged, so this is at least some reproducability.

Running under strace had this output at the tail end
