QAbstractItemModel ASSERT on initial library scan

[Sean M. Pappalardo]

When running Mixxx with no config and it tries to do an initial scan of my music files, I get the following:

Debug [Main]: Promo dir: "F:/Mixxx/Branches/1.11/mixxx/dist64/promo/1.8.0/index.html"
Fatal [Main]: ASSERT: "last >= first" in file kernel\qabstractitemmodel.cpp, line 2413

Running Mixxx again seems to work okay until I request a library rescan.

This is v1.11 r3341 on Windows XP x64.

This does not happen on Windows x86 so now I wonder if I messed something up when building Qt...

Hey Sean -- how frequently do you use the library on this x64 machine? Is it possible you've run Mixxx hundreds of times (with the same mixxxdb.sqlite)? If so then this is possibly a dupe of Bug #1054836 which only happens on 1.11 if you have hundreds of history playlists (a new one is created every time you run Mixxx).

[RJ Skerry-Ryan (rryan)]

Hm. You say "no config" but does that mean no library?

[Sean M. Pappalardo (pegasus-renegadetech)]

Correct. I delete the whole %userprofile%\Mixxx folder when testing for a bug.

[RJ Skerry-Ryan (rryan)]

Could you try with the latest builds? This was reported before we made the
switch to Qt 4.8.3.

Mixxx now uses GitHub for bug tracking. This bug has been migrated to:
