Well, I tend to agree with Günter that the segfault he mentions is a serious
bug, even if it only happens rarely and the package is mostly usable.

This would be a compelling reason for stick to 2.0.6.  Are you just
supposing that or do you have some evidence that 2.0.7 is buggy?

Well, we can always remove the version restriction when backporting a
package and document where the pacakge would fail.

It is difficult to take the decision without evidence that 2.0.7 is buggy.
Let us discuss a little bit further about this.  Günter?
