I have no files with such a name but it may be a similar reason... I will try some of the typical config files like .~ or things like that and come back if any of those fixed it...

I got this: ''' Debugger entered--entering a function:

I have replaced hostname and username with those words instead. What do you think? May it be the tramp-wait-for-regexp or the dired-find-file. I don't know whether last things before the kill -12 are on the top or on the bottom...

I don't understand what is the string ".editorconfig" doing there, but I will try, as it may be related with the error. Although I have realized the error happens on my laptop or home computers so I will have to try out after coming back from work. Thanks and I will come back to say if it is fixed...

USR2 kill signal

I thought it was doing the same in all my computers, but now I realize it is working flawlessly on my work computer (it is usually the one I connect to more than the other way around). So I will have to wait to come back home to test... Thanks!
