Going to assume this was a corrupt pref value or something.



Feel free to re-open this if you have any more feedback to provide.

Well, that doesn't match the file that should be there, but that might 
be from you adding the debug statements, etc...



Anyway, I can't reproduce the problem, and I still have no idea how 
you have a single object in that variable as opposed to an array of 
objects.



Can you give me the exact steps you followed to reproduce?

today i've downloaded horde-3.3-rc1.tar.gz and thats horde I'm using. 
I've copied there(to the extracted horde dir) ingo, imp and turba from 
previously installed horde 3.1(installed from stable debian repo). 
Configuration is merged with the old one..just few changes was needed.



this is md5sum of file Maintenance.php horde is using..



000b1dcabc4fe9f2c0e69f6c290b87b4  /usr/share/horde3/lib/Horde/Maintenance.php

Strange. The only way that makes sense is if you are using an older 
version of the Maintenance package, like the one that would have been 
in Horde 3.1.x. Is there any way that is the case, maybe the new 
framework packages were not installed or Horde is using a different 
include_dir than you think it is?

I'm sure thats all that is displayed.



string(212) 
"O:20:"Maintenance_Tasklist":6:{s:7:"_module";s:3:"imp";s:7:"_target";s:56:"/imp/redirect.php?Horde=904a7a55a20fe149259456d283b93570";s:9:"_postdata";N;s:6:"_tasks";a:0:{}s:8:"_addFlag";b:0;s:10:"_processed";b:0;}"

Hm, not what I was expecting. Are you sure that is the *entire* output 
of the dump? i.e. Is there something like 'Array => Maintenance_IMP   
or similar?

Hi,
Maintenance_Kronolith
string(212) 
"O:20:"Maintenance_Tasklist":6:{s:7:"_module";s:3:"imp";s:7:"_target";s:56:"/imp/redirect.php?Horde=78f9cff68735c775ff5901db9a0fdb24";s:9:"_postdata";N;s:6:"_tasks";a:0:{}s:8:"_addFlag";b:0;s:10:"_processed";b:0;}"

I think I know the issue, but to verify what is going on can you add 
the following lines in the _retrieveTasklist() method and post the 
output?





echo get_class($this);



and



var_dump($_SESSION['horde_maintenance_tasklist']);

turba  H3 (2.1.3)

ingo H3 (1.1.2)

horde 3.3-RC1

lronolith H3 (2.3-RC1)

imp H3 (4.1.3)



newly created database (mysql) = empty. After clicking on cal app in 
menu just black window is showed.



in php.log is the reason



[12-zá&#345;-2008 15:08:24] PHP Notice:  unserialize() [<a

unserialize($_SESSION['horde_maintenance_tasklist'][get_class($this)]);

470         } else {

471             $this->_createTaskList();

472         }

473     }



so from some reason - im not php programmer so i dont know why 
:)..tasklist variable is not created in true branch of if.



I've: tried workaroud :)..commented all but line 471 and it works..but 
i suppose thats not best option :)..after restarting apache and 
uncommenting it again..problem is back.



Maybe there is something wrong with my session..then priority should 
be lower...but...



Thanks
