Redmine

Hy,

Something probably weird here.
I copied an issue with 2 files attached.
In the copy issue, I added a file inside, I validated the issue, navigate etc...
Later, I realised that one of the 2 files coming from the copied one was useless. I clicked on the bin icaon and then redmine crashed.
Here is the message :
