The "recaller" application does this to me.

Currently, the oonly way to stop hilldon-home from crashing, is to not use the app/wigdet.

I faced the same trouble and it mostly happens after an alarm is triggered.

Then the calendar widget no longer refresh.

I use only few widgets - not using DCEW, nor recaller. Here are what I have on my desktops: calendar, maxcpu, ConnectNow, Data Plan monitor. Everything else are shortcuts, contacts and bookmarks.

As a work-around to get back your desktop, you can remove a widget then you get "hildon-home" does not respond. Close it. Then you have to insert back your widgets.

I removed maxcpu from by desktops and the issue never appeared again. 55 days uptime !

This could be true. As soon as I removed DCEW and installed it again immediately, almost everything was fine.
I only experienced this seldom. But after deinstalling/installing, this did not happen anymore.
Just make sure, that you remove the file /home/user/.desktop_cmd_exec, as it seems, that this config file is somehow screwed up.

Yep, this seems one of the reason(s).
At the moment I do experience this only when alarms are triggered. Then I can not snooze/switch off, and hildon-home freezes.
I just switched to alternate worldclock from CepiPerez / ade
(http://talk.maemo.org/showthread.php...ght=worldclock) and am still testing, but it looks good.


BTW:
I already posted some scripts some time before in some other thread, but here I go again:
Unzip the att at any place you like (I propose /home/user).
You will find 4 scripts, which you may make executable or just call them with
sh home
sh desktop
sh plugins
sh pluginssave

The first thing you should do is set up all your widgets and make a safe backup of the widget configuration with
sh pluginssave

Calling
sh plugins
will now restore all your applied widgets.

Calling
sh home
will kill hildon-home and reenable your widgets.

As a gift:
Calling
sh desktop
will restart hildon-desktop, necessary sometimes, as it eats CPU/battery from time to time (solved).
