WriteDocument SVG not working when debugging

Question

Hi,
I am trying to save a file as svg (silently in the background), by doing the following:
ai::FilePath svgFile;
err = sAIFilePath->NewFilePath(svgFile);
err = sAIFilePath->Set(ai::UnicodeString("/Users/tom/tmp.svg"), true, svgFile);
err = sAIDocument->WriteDocument(svgFile, kAISVGFileFormat, false);
When running the plugin from Xcode (in debug mode) this isn't working. There are no errors but the svg file stays empty and untouched. If I try to manually "File" -> "Save as" ->  "SVG" -> "Save" it shows a dialog with a button "SVG Code...". If I click on it nothing happens! Is the svg feature broken somehow?
Now for the weird part; if I just run Illustrator and use the plugin that way (not in debug mode), none of the above problems occur.
I am totally stuck, any help is greatly appreciated.
Best,
Tom

I have isolated the problem somewhat. I think it is a bug, maybe someone can try to reproduce this?
Open one of the examples provided as part of Adobe Illustrator CC 2014 SDK (I used annotator).
Make sure AI CC 2014 is loading the samples.
In AI CC 2014 preferences, go to "Plugins & Scratch Disks"
Check additional Plugins Folder
Choose the dir in which the sample project will be build: [...]SDK/samplecode/output/mac/debug
In Xcode (6.1), Product -> Scheme -> Edit Scheme.
Select Run (debug) and use the following settings:
build configuration: debug
executable: Adobe Illustrator CC 2014.app
check debug executable
Product -> Run
Now, Xcode will debug the sample in AI.
Create a new document
File -> Save as..
Choose SVG as the format and click save.
A Dialog will appear, keep the default settings and click Save.
In my case, this results in a dialog with the message: The operation cannot complete because of an unknown error. [PARM]
Note that the problem only occurs in AI CC 2014. In AI CC it works correctly.
Thanks,
Tom
