crash while pushing videos to device

[Selene ToyKeeper]

I consistently get a mediascanner crash when I push videos to my device after flashing it. These are the commands I run to send the videos:

adb push ~/.cache/mwc/videos.tgz /home/phablet/Videos
adb shell 'cd /home/phablet/Videos && tar xfvz videos.tgz && rm -f videos.tgz'

The crash happens during the second command, extracting or removing the tarball. The video tarball itself is the same one we used for the MWC demo a long time ago.

The resulting crash file is attached.

I recall seeing this frequently for a long time, but the crash file I attached is based on krillin-proposed rtm image 124.

I'm curious if this happens with the same videos if you use MTP instead of adb push? Technically we do not support pushing media to the device via adb.

What does .cache/upstart/mediascanner-2.0.log say about this crash?

Sorry for the delays, I had forgotten about this bug.

I tested again today (arale rc-proposed 174) and it appears to still happen. I don't recall seeing it via MTP, but that's not automated so the MTP case isn't touched as often. Attempting it just now, I didn't get it to fail... but sending via mtp is also a lot slower than untarring a file locally on the phone so it might not stress the device much.

The tarball I mentioned earlier is:
http://toykeeper.net/tmp/phablet/videos.tgz

I suspect that this bug is actually in one of the platform specific codecs rather than media scanner itself.

We've done about all we can to mitigate these problems. You'll notice that the new crash you've attached is in a different executable now: the codecs can only cause an extraction specific subprocess to crash now, with the main scanner daemon continuing on.
