O.k. I finally managed to get also your
fix-cursor-recapturing-sliders.patch in my (honestly said: your)
audacity-package at apt.klaumikli.de/testing (no changes needed; no
idea why it didn't work the first time!) and I also added the
configure flag '--with-lv2=system' to Debian/rules. 

So far it workes fine, also adjusting the sliders for volume and pan
now works, but again every time I try to attach some lv2-plugin
audacity crashes - and this with all plugins I tried the last 30
minutes (maybe 20 or so). 

I tried to debug the problem and got this:

Program received signal SIGSEGV, Segmentation fault.
0x0000000000999500 in LV2EffectDialog::HandleText() ()

In audacity-2.0.6/src/effects/lv2/LV2Effect.cpp I found your comment
from the wxWidgets-3.patch:
"   // wxWidgets calls OnTextCtrl during creation
   // of the text control, and LadspaEffectDialog::OnTextCtrl calls
HandleText,
   // which assumes all the fields have been initialized.
   // This can give us a bad pointer crash, so manipulate inSlider to
   // no-op HandleText during creation. "

But there my wisdom has its end ;-)

I hope this helps at least a little bit!
