<pre style="white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">Why is it related? Who is modifying the entries variable? It's used in 4 places in the file, and actually there's no way to remove stuff from it, so I don't see how it is related to the bug you point.</pre>

<pre style="white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">They are only related because replacing qDeleteAll() with manual deletion fixed the crash for Boudewijn. Since my understanding ended there, I suggested to post a review request.</pre>

Qt 4.8 changed qDeleteAll to rely on the container being immutable.
The patch detaches the container, what allows safe operation despite - what's likely happening as it seemed the core issue back than - the container is altered by the deletion of one or more of its items (eg. the items deconstructor delists itself)
An alternative solution would be to pass the to-be-deleted objects class a static member flag to skip self delisting and set that around qDeleteAll() (which would be followed by an erase())</pre>

<pre style="white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">Please look at the code and tell us where the item deconstructor delists itself from the list.</pre>

<pre style="margin: 0; padding: 0; white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">While I haven't been able to reproduce the issue on Linux, many Krita users encounter a crash in the destructor of KArchiveDirectoryPrivate, where all entries are removed with qDeleteAll.
This patch removes the use of qDeleteAll.
I'm not 100% sure whether this is correct, but it works for me with the Windows build of kdelibs I use.</pre>
