Patch against Soprano (quick and dirty hack)

I never experienced this bug and have no way of reproducing it. Thus, I need someone to test patches for me.

The first one is this Soprano patch which is no real fix but a workaround which hopefully helps to pin down the problem.

If this patch solves the bug then I know what the problem is and can fix it properly. If this patch does not solve the problem I can at least exclude one possibe reason.

Thanks for the patch, I applied it and installed soprano packages, nevertheless I still get the crashes (as stated in #277379)

Actually I realized today that these are 2 different bugs (#280818 and this one) which stem from the same problem in two different places. #277379 is actually a duplicate of #280818 for which I will have a patch soon. Thanks for testing.

Hello! Sorry to be the bearer of bad news, but this project has been unmaintained for many years so I am closing this bug. Development has moved to Baloo, please try again using the latest version and applications, and submit a new ticket for frameworks-baloo if you still have an issue. Thank you!
