(this is mostly for the other people on this ticket)
This projects seems dead for all intents and purposes. FWIW,
I've switched to rb-appscript and it works wonderfully. Be sure
to download ASTranslate, it helps convert applescript to
rb-appscript.
I'll be publishing my omnifocus gem in the next day or so if
you'd like to use it as an example. |

Is there any intention of fixing this? Should I find an alternative
to rubyosa? Why isn't this assigned to anyone?

I'm also getting this, with a clean XTools install from 10.5.6
disks (on a 10.5.7 Intel iMac). How do I move back
to libxml-ruby-0.5.4? |

Hi Len,
Thanks for the patch. However, I'd much rather fix the base
rxml_attr_value_get method.
From the libxml documentation, xmlHasProp and xmlGetProp both
check DTD's, so that doesn't seem to be the issue. The patch
as attached does what the code already does, with one difference:
current code: xmlHasProp -> attribute -> xmlGetProp ->
value
patch: xmlGetProp -> value
The issue I have with the patch is that it would not fix:
attr = node.get_attribute('foo')
attr.value
Looking at the stack trace, best guess is that the attribute
returned by xmlHasProp has a NULL name. Of course you have to
pass a name to xmlHasProp so that doesn't really make a lot of
sense - but the call to xmlStrEqual is suspicious.
Anyway, do you have a test case? If so, this will be easy to
fix.
Thanks - Charlie |

This is because rxml_attributes_attribute_get calls xmlGetProp
on an attribute 'access' from the sdef.dtd
Quick and dirty fix

I too see this problem. I'm running 10.5.4 on an iBook G4 (PPC.)
The stack trace appears meaningless - it's in the middle of garbage
collection. I've been able to replicate the problem every time
I run the following code in IRB:
require 'rbosa'
keynote = OSA.app('keynote')
Here's what crashreporter gives:
