I found that after an update from LibO 3.6.3.2 release to "LibreOffice 3.6.4.1 rc" German UI/ German Locale [Build-ID: a9a0717] on German WIN7 Home Premium (64bit). For LibO 3.6.3 I had deactivated Extenison "E-Porto" because for the lots of problems that extension caused. After LibO version Update the Extension was active again. I am pretty sure that this also is a problem for more early versions, and I don't know whether other extensions are affected - I simply did not test yet.
It indeed appears that disabled-status of extensions gets lost when they are checked for consistency after a LO update has been detected.

The above two commits should fix the disabled-status now across a LO update. Requested backport to libreoffice-3-6 (towards LO 3.6.5, <https://gerrit.libreoffice.org/#/c/1119/>) and libreoffice-3-6-4 (in case of an additional LO 3.6.4 RC build, <https://gerrit.libreoffice.org/#/c/1120/>).
