Error saving project; .mlt with 0 bytes

Willian_Cruz · June 24, 2019, 10:45pm

Just upgraded to 19.06.15 and now when I work in a project created with a previous version and try to save changes, I get an error message.

temp

Application log:

[Debug ] <Mlt::Controller::saveXML> writing temporary XML file "D:/Dropbox/Fotos/vadebike.org/videos/2019/2019-06 Como defender as ciclovias em Audiencias Publicas/shotcut-MQ6720.mlt"
[Error ] <Mlt::Controller::saveXML> backup file already exists "D:/Dropbox/Fotos/vadebike.org/videos/2019/2019-06 Como defender as ciclovias em Audiencias Publicas/1 - backup - EH6720.mlt"

After that, project file is with 0 bytes. If I use “save as…” and choose another file name, it works fine, so every time I want to save I am creating a new file by now.

Is this problem specific to using Dropbox?
Before overwriting the existing file, Shotcut now tries to rename the existing file to have a backup in case there is a problem writing the new file. After a successful save, it tries to remove the backup file. There was a problem during one of your saves leaving the backup. If the backup already exists, saving will fail as you report here. You must remove the backup file to save it under the target name.

Yes, tried in a folder out of dropbox and it works fine. But if I save it in any dropbox folder, at the second save it happens again.

If I look for that backup file it is not there. Dropbox also didn’t sync it (can’t find it via web site).

It seems that the file IS there, because of the error, but if I look for it, it is not there. Very strange.

Any test I could do to track this?

(I am not doing anything I wasn’t doing before upgrading)
