All this is while running nightly builds. - Running the build updated Saturday 06/21, I deleted the 4 collections that are by default on the homescreen (Social, Games, Music, Entertainment). - Sunday, I got an OTA update. 1) The 4 collections are back on my homescreen. The return of the revenge of the deleted collections! 2) I can't remove them anymore... I get the "Delete Collection" dialog but nothing happens, except this very strange error in logcat: I/GeckoDump(15211): XXX FIXME : Got a mozContentEvent: activity-choice I/Gecko (15211): [Parent 15211] WARNING: waitpid failed pid:15563 errno:10: file ../../../gecko/ipc/chromium/src/base/process_util_posix.cc, line 261 I/Gecko (15211): IPDL protocol error: Handler for AsyncMessage returned error code I/Gecko (15211): I/Gecko (15211): ###!!!

We should find out if they are not really deleted from datastore, or we are running our upgrade scripts when we should not be.

I think this is the same problem as bug 1028692.
