synaptiks crashed with KeyError in __getitem__(): u'No such property: NAME'

[Jonathan Trinham]

[Impact]
When the option to disable the touchpad when a mouse is plugged in synaptiks crashes on plug events (including wakeup from sleep/hibernate). Leaving users unable to use this feature.

[Test Case]
* Start synaptiks
* Enable the option 'Automatically switch off touchpad, if a mouse is plugged'

[Regression Potential]
None. The code section in question currently crashes, at worst it continues to crash.

[Other Info]
Crash is prevented by using .get() rather than [] accessor and falling back to DEVNAME as possible replacement property.

--------

I'm not sure what caused this to happen.

This worked for me:

1. run synaptiks

2. make sure the box is not checked to 'automatically switch off, if a mouse is plugged'.

3. click 'apply'

4. click 'ok'

Update:

I rebooted computer and resumed my work and the mouse froze up again. I repeated the same steps I posted in #2 and the touchpad was working again. This is just going to take some sorting. Plugging in an external mouse and changing the same settings every time you start your computer does not constitute a proper workaround. These things must be tolerated with alpha code. This issue only began after:

 'gnome-settings-daemon crashed with signal 5 in _XReply()' Bug #907052

[note] also at the same time as touchpad bug my nautilus began to look different (and not in a good way), see attached screenshot:

[Lisa Simpson (lisa-p)]

I'm on Pangolin and it's happening to me. My only setting is to disable the touchpad while typing. My touch pad is located nearly where my writs are so I bump it frequently while typing. So I set it turn off when I'm typing. The downside is that my touch pad will disappear completely leaving me stuck trying to wrack my brain for keyboard shortcuts to get to the terminal to restart it :/

[Theresa (theresa)]

I think I have a similar problem:

a) synaptiks crashes at startup....touchpad is "frozen" for about 30 seconds or so...

b) when I run synaptiks manually in the terminal i get the following:
QDBusConnection: session D-Bus connection created before QCoreApplication. Application may misbehave.

what am I doing wrong here?

any idea? ;)

Just rebooted 12.10 and tapping on the pad stopped working. Ran into this.
Workaround for me
synclient TapButton1=1

[Nick Leverton (nick-leverton)]

I am experiencing this crash from synaptiks every time i close and reopen the laptop lid. Not even suspend/hibernation is required to trigger it: it just happens. Apport refuses to report it as it says this bug is duplicate and there are too many reports already.

It would be really nice to get this paper cut fixed. It has been a problem right through for the last year or more. Hopefully bumping it ...

[Artúr Poór (gombocarti)]

For me, it usually happens when I unplug the logitech unifying receiver. But after the crash it seems everything work and no further crash happens. I use kubuntu 12.04.2. I hope it helps.

[Kevin Fleischer (t-contact)]

I experience the same behaviour as #7.
When I put my laptop to sleep by closing the lid and I reopen it the next day, synaptiks will be crashed.

Actually that is a crash in ID_SERIAL which is equally silly, however not the same crash.
