Bug#962870: tracker-miner-fs: Repeated SIGABRT crashes due to file_tree_lookup assertion failed

[Tomáš Szaniszlo]

Package: tracker-miner-fs
Version: 2.3.3-2+b1
Severity: normal

Hello, in my user journal I noticed that the tracker-miner-fs binary frequently
crashes, a few times every minute. I did not install it explicitly, nor am I
aware of specifically configuring it.
