[digikam] [Bug 365684] Tags Manager : Crash when deleting a tag from the list of tags

[Olli Lupton via KDE Bugzilla]

https://bugs.kde.org/show_bug.cgi?id=365684

--- Comment #20 from Olli Lupton  ---
Hi,

Sorry for the delay.
I also saw strange characters in the collection paths when I migrated by 4.X
database to 5.X, and had to re-add the collections to fix this.

However, this does not explain the crashes I have seen. I was able to reproduce
the crash in a fresh 5.X session (having deleted the .db files and all the
configuration files I know about).

The fact I am not able to reproduce the crash using a different user account on
the same system suggests to me that the problem is either that there is some
other old configuration file I don't know about, or digikam is somehow being
affected by environment of one of the user accounts (PATH,DYLD_LIBRARY_PATH
etc.).

Hi,

I made sure all of those locations were removed, but it doesn't stop the
crashes using my main user account. I also tried removing:
~/Library/Saved\ Application\ State/digikam.savedState/
~/Library/Caches/digikam/
~/Library/Application\ Support/digikam/
along with re-removing the .db files, and I still get crashes.
Can you think of any other possible persistent configuration or caches?

Hi,

I just tried, I get the same crash using the GUI on the right-hand-side as
well.

I have tried experimenting with a clean database + 1 blank-white JPG created in
an image editor (=> no tags initially)

Remove DB files -> start digikam -> choose collection location -> add tag
(Test) to file (gives 'Tag name already exists' error but apparently succeeds)
-> Apply -> close digikam -> restart digikam -> (tags list now shows 'People'
in addition to 'Test') -> delete 'Test' -> crash

This crashes reliably for my main user account.
I tried to replicate in a 'clean' user account on the same machine, but there
the same prescription does not crash. I am, therefore, wondering if there is
some bit of old configuration lurking somewhere that I am failing to clean up,
and that is causing the problem (somehow).

Currently to make a 'fresh' start I am deleting the three .db files, and
removing ~/Library/Preferences/digikam*
Is there some other configuration or cache hidden somewhere else?

Hi,

I'm using OS X 10.11.4.

few others. Here are the database statistics:

I tried catching the crash with Xcode, but there is very little information
there.
Are the precompiled bundles on http://download.kde.org/stable/digikam/ supposed
to have debug symbols?  Xcode just shows the instructions, which are rather
unhelpful.

--- Comment #7 from Olli Lupton  ---
Hi,

I just tried as you suggested, re-naming the database files and letting it
rebuild them.

This does not fix the problem. I removed a tag and it crashed again, see below.

Is there another way of running the OS X packaged build in some debug mode that
would provide more useful information?

--- Comment #5 from Olli Lupton  ---
Thanks for looking into this!

Database type: SQLite (created with digikam 4.X)
Database location: local SSD
Collection location: local HDD (machine has 1 SSD, 1 HDD)

I ran in a terminal as you suggested. The only output triggered by deleting a
tag is:

digikam.geoiface: 
digikam.geoiface: 
digikam.general: Stacked View Mode :  0
digikam.general: Delete Shortcut assigned to tag  610
digikam.geoiface: 
Segmentation fault: 11

Which doesn't seem that informative to me. In case it helps, here are the first
few lines printed by digikam after startup. Let me know if there's anything
else I can try?

--- Comment #1 from Olli Lupton  ---
Two further comments:

1. The operation does seem to succeed (i.e. the tag is removed), despite the
crash.
2. I see a similar crash if, in the tag manager, I try and move a tag (e.g.
SomeName -> People/SomeName).

[digikam] [Bug 365684] New: Crash when deleting a tag from the list of tags

[Olli Lupton via KDE Bugzilla]

https://bugs.kde.org/show_bug.cgi?id=365684

Bug ID: 365684
   Summary: Crash when deleting a tag from the list of tags
   Product: digikam
   Version: 5.0.0
  Platform: Mac OS X Disk Images
OS: OS X
Status: UNCONFIRMED
  Severity: crash
  Priority: NOR
 Component: Tags
  Assignee: digikam-de...@kde.org
  Reporter: digikam.2759c...@olupton.com

Digikam consistently crashes if I remove (right click, "Delete Tag") a tag in
the tag manager (2nd tab, left hand side of screen). This happens regardless of
whether or not the tag is applied to any images.



Reproducible: Always

Steps to Reproduce:
1. Install
http://download.kde.org/stable/digikam/digiKam-5.0.0-MacOS-x86-64.pkg
2. Go to tag manager (2nd tab on left hand side of screen)
3. Right click on a tag and click "Delete Tag"

Actual Results:  
Crash.

Expected Results:  
Tag should be removed from all files it is applied to, and the tag should be
removed from the list.
