dpx Bus Error

[meanleybh]

I seem to be running into some type of bug when trying get information, or do conversions to DPX frames:

$ identify -verbose /Users/*********/Desktop/chart.dpx
Bus error

$ convert /Users/*********/Desktop/chart.dpx -define dpx:television.time.code=10:00:02:15 /Users/********/Desktop/chart.0000000.dpx
Bus error

however I can seem to use the "identify" command without the "-verbose" flag alright:

$ identify /Users/***********/Desktop/chart.dpx
/Users/************/Desktop/chart.dpx DPX 960x540 960x540+0+0 10-bit DirectClass 1.979mb

I am very new to this program (essentially today...), so this very well could be something that I am doing wrong...., but if anyone else is running into issues, or could perhaps point me in the right direction... That would be greatly appreciated.

Thanks!

Post a URL to chart.dpx here so we can download it and reproduce the problem. Thanks.

Thanks for the quick reply!

Here is the link to the file....I have blurred it out, because it isn't mine, and the other DPX files that I have can't be released because of NDA's and such..., but just to be clear, the issue seems to be with all DPX files on my system, not just this one specific file....

I am running Image Magick under OSX 10.5.7 on a MacBook Pro if that helps at all...

Let me know if you need any other information. Thanks!

Thanks again for the quick response,

I will try a reinstall to see if I can track down the issue...

Thanks.
