Aaron, you recently worked with barcode, can you please look into this?

[Tom Davidson (tjd-mit)]

From the error message, the original user appears to have entered double-quotes around the number. I.e. "1251455", so the error reported is actually expected behavior. Search 'barcode' for other problems relating to this extension.

[Aaron C Spike (acspike)]

I think this is actually a symptom of generalized quoting problems with effects. The problem is something like the user didn't enter quote and they appeared, but were not stripped by standard command line parsing because they were unnecessary.

[Tom Davidson (tjd-mit)]

I see. Bug 168783 reports the same problem (That bug reported multiple issues, and launchpad will only allow a bug to be a dupe of one other bug, so I couldn't mark it as a duplicate of this one)

[Aaron C Spike (acspike)]

Ted I think this is your arena because it concerns quoting on linux.

[Tom Davidson (tjd-mit)]

Has anyone been able to reproduce this bug on a recent SVN version? I've never seen it on Linux, and Aaron reports that barcode is currently working on Windows...

I second the report. Mac OS X 10.4.11 Intel, Inkscape 0.46, EAN13, either 12 or 13 digits. The other barcode codings, too.

Hello, I work under Intrepid Ibex.
I made some experiments in inkscape :

Sorry forgot UPC-5

Barcode is generated and got message :

[jazzynico (jazzynico)]

I can reproduce it on Ubuntu 9.04, Inkscape 0.46, but NOT with rev. 21690. Thus I think it can be marked as fixed.
Please test with a recent dev build and reopen this report if you still have the bug.
