Dolphin: 14.11.97 (beta from Arch kde-beta repo) using KDE 4.14.3 (but using KDE frameworks 5.5, plasma 5.1.2) When trying to tag large amounts of files (>60) a segmentation fault seems to occur most of the time. It seems the more files tagged the greater the chances of a crash. I've also noticed this happen in previous versions at least from two months ago. The only suspicious entries I see in the journal are: Dec 17 21:10:17 system baloo_file[859]: Could not obtain lock for Xapian Database. This is bad In .xsession-errors the following seems related: --------- dolphin(3608): Bananana Error dolphin(3608): dolphin(3608): Bananana Error dolphin(3608): Could not obtain lock for Xapian Database. This is bad dolphin(3608): dolphin(3608): Could not obtain lock for Xapian Database. This is bad dolphin(3608): Serious Error: dolphin(3608): Error opening table `/home/david/.local/share/baloo/file/record.': Couldn't open /home/david/.local/share/baloo/file/record.baseA: Too many open files Couldn't open /home/david/.local/share/baloo/file/record.baseB: Too many open files DatabaseOpeningError: Error opening table `/home/david/.local/share/baloo/file/record.': Couldn't open /home/david/.local/share/baloo/file/record.baseA: Too many open files Couldn't open /home/david/.local/share/baloo/file/record.baseB: Too many open files KCrash: Application 'dolphin' crashing... KCrash: Attempting to start /usr/lib/kde4/libexec/drkonqi from kdeinit KCrash: Connect sock_file=/home/david/.kde4/socket-dellt3400/kdeinit4__0 ------ So it looks like perhaps I need to adjust the amount of open files allowed somewhere in my configuration. I will investigate,do that and report back, however, I don't think Dolphin is supposed to crash under this condition and probably should handle it more gracefully.

Steps to reproduce: 1. Create a large number of files. 2. Using dolphin add a tag to these files. It crashes when it reaches the 250th file.
I'm guessing that the Dophin being used is the Qt4 version. When Dophin moves to KF5, this should be fixed as it will no longer be writing to the Baloo database directly.
