Hi,
Building the latest version on linux from github I get the following error:
ERROR IN CLASS image_writer_t: cannot open bus/./images/MailCartNew.png
The problem is that the filename is MailCartNew.PNG and the case-difference causes the file to be missed on case-sensitive filesystems.
> ls bus/images/MailCartNew*
bus/images/MailCartNew.PNG
Regards,
Mark
Thank you for the report - now fixed.
