<br>
thank you for merging the patch, it definitely solves my issue ;-)<br>
<br>
In the mean time I've also started looking into the segfault when PVD<br>
files link to other PVD files. This was easy to find and fix, so I'll<br>
prepare a new patch soon, but I'll need some help to implement actual<br>
proper nested PVD support (assuming it's ever needed). Where would be<br>
the most appropriate place to discuss this? Here? the -developers ML?<br>
A pull request for a WIP patchset?<br>
