Description Frédéric Virot 2011-05-27 07:33:26 UTC
Application: dolphin (1.6.1)
KDE Platform Version: 4.6.2 (4.6.2)
Qt Version: 4.7.2
Operating System: Linux 2.6.38-8-generic-pae i686
Distribution: Ubuntu 11.04

-- Information about the crash:
- What I was doing when the application crashed:
I was browsing the file system, in my home directory

- Custom settings of the application:
the directories that were being entered at crash time contain quite a few sub-directories (ca 40) each with a different customized icon.

The crash can be reproduced every time.

-- Backtrace:
Application: Dolphin (dolphin), signal: Bus error

Comment 1 Michael Pyne 2012-05-21 03:22:24 UTC
Git commit 561e6494bdd9a02cc8feef649f7dbbd40a1456c3 by Michael Pyne.
Committed on 20/05/2012 at 00:13.
Pushed by mpyne into branch 'KDE/4.8'.

kshareddatacache: Validate cache page size.

This commit ensures that the cache page size is actually a power-of-2
and within the band of possible sizes that could possibly have been set.

If this is not the case the cache is assumed corrupted and reset.

This should help with any cache-corruption bugs caused by a wrong cache
page size (although these don't exactly make themselves obvious). More
fixes to follow...

This one /should/ fix 274252 outright and may be of interest to several
others.
