[BioC] arrayQualityMetrics NULL XML-node Error; Anyone still getting this?

Dear Eric

yes - cairo 1.2 is way out of date, and I am pretty sure that that is 
the culprit (it was before, in similar cases). You'll need to ask your 
server admin to update that. The cost of using bleeing-edge tools... :)

	Best wishes
	Wolfgang

>> Dear Wolfgang,
>>
>> Thanks for taking a look and for your quick response.  I will look at the potential upgrades you are suggesting, but I see that several key versions you are using are unstable or development versions including R, your browser, and AQM itself.
>>
>> I need to produce software for a production system rather than personal use, so I hesitate to introduce dev/unstable dependencies.  Do you know offhand the most recent combination of stable versions that work together correctly, for instance with Bioconductor release 2.8?
>>
>> Thanks,
>> Eric

>>> Hi Bioconductors (hopefully still including Wolfgang),
>>>
>>> I have updated my packages, as per this list's posting guide, but to no avail.  I have also searched the archives, and I discovered this thread where someone had a very similar problem (http://thread.gmane.org/gmane.science.biology.informatics.conductor/31622/focus=31666).  I do not see there any solution.  It's been about a year since that thread circulated, so I was wondering if anyone else has encountered this XML problem when running arrayQualityMetrics.
>>>
>>> It is not clear that my error is exactly the same as what James (from the above thread) encountered, but I'm thinking it's likely related.  Maybe there is a parallel code block to the one throwing an error for James that wasn't fixed and is only now being observed.  The differences from James's report follow:
>>>
>>> 1) I do get sections 4 and 5 in the index.html report file.
>>>
>>> 2) I have a notice beneath the caption for Figure 3 which reads: "Note: the figure is static - enhancement with interactive effects failed. This is either due to a version incompatibility of the 'SVGAnnotation' R package and your version of 'Cairo' or 'libcairo', or due to plot misformating. Please consult the Bioconductor mailing list, or contact the maintainer of 'arrayQualityMetrics' with a reproducible example in order to fix this problem."
>>>
>>> $ pkg-config --version cairo
>>> 0.21
>>>
>>> $ xml2-config --version
>>> 2.6.26
>>>
>>> The binary libcairo file installed is at /usr/lib64/libcairo.so.2.9.2
>>>
>>> Figures 6 and 12 *are* interactive, which leads me to think it could be either a version mismatch issue between libcairo and SVGAnnotation or a code issue in the arrayQualityMetrics package itself.
>>>
>>> I also have another case with the same error manifesting slightly differently, but I figure it's best to have everything working correctly for sample code from the vignette first (http://www.bioconductor.org/packages/2.8/bioc/vignettes/arrayQualityMetrics/inst/doc/arrayQualityMetrics.pdf and below).  I notice that some of my versions are slightly newer than those from the vignette.
>>>
>>> Details:
>>> * R was run as: R --vanilla
