Failed to upload files with "-120x60" in the name

While testing the upgrade to the new version of Xray we have verified that it is consistently failing the upload of files to a test step if it contains a name with a string like "-NNNxMM" with N and M being numbers (e.g. nav-logo-quartz-2-1-120x60.png)

Could you please check and correct this problem.

Thank you for your time.
