--- Comment #41 from Roland Baudin roland65@free.fr --- My catalog is ~200 MB (~10000 images) and I don't have such issue with wine 1.7.21.
You could first try to patch wine 1.7.11 with these 5 patches, or you could also try to upgrade to the recent 1.7.24 version (I didn't test it).
Perhaps, the problem is in your catalog, I don't know if there exist some way to repair and clean an LR catalog? RB
