Bug 350370

Application: baloo_file (5.6.2)

Qt Version: 5.4.1
Operating System: Linux 4.1.1 x86_64
Distribution: Ubuntu 15.04

-- Information about the crash:
- What I was doing when the application crashed:

Baloo_file indexer crashed after deletion of directory with huge amount of files.

.xsession-errors log contains:

terminate called after throwing an instance of 'std::length_error'
  what():  basic_string::assign

The crash does not seem to be reproducible.

-- Backtrace:
Application: Baloo File (baloo_file), signal: Aborted
