How does it crash? Straight to desktop, or does a message pop up? |
|
It gives a stack dump. Let me add that

And does this happen every time you open the example file? |
|
Yes

Different versions of GRIP 1.5.1 seem to be generating different, incompatible XML files. Some versions create a file that starts with |
|
It's a bug with the library we're using to generate and read the XML save files. It defaults to use class names like @nollchr has had this problem before. Since he's the only person who's experienced this, there's something weird going on in his computer that causes the XML library to do this. |

Lucky me! Our team has several identical laptops with roughly same configuration. I'll try this on a few others tomorrow.

What causes some installations to behave differently from others? |
|
We have 2 people with the problem |
|
Try waiting 5-10 seconds after launching GRIP and see if this still happens. |
|
Doesn't work |
|
Can you upload the save file to a gist and share it here? |
|
That explains the problem... The absolute paths are being used instead of the alias. |
|
@vanjac can you zip and upload the entire |
|
I will ask one of the people... Another problem: after the exception occurs, GRIP completely freezes. Even if this gets fixed it seems like there's a problem with exception handling. |
|
I'm one of the people, can upload later this evening |
|
Great. RE: the freezes. Can you open a separate issue detailing what exactly you did to make it crash? |
|
There's a 10 MB file limit, and the zipped file is 100 MB. Are there specific files that we could upload instead of the whole thing? |
|
No, I need the whole install. You could use google drive and share a link. |
|
Here you go: https://drive.google.com/file/d/0B2i21SMA63Y3LXN5UUQ0RlJkbHc/view?usp=sharing. I had put it in Program Files instead of AppData. |
|
I think that archive is corrupted. 7zip says it's a zip archive, not a 7z, and opening it as either is unsuccessful. |
|
I think Google Drive freaked when I uploaded it with drag-and-drop. This link should work: https://drive.google.com/open?id=0B2i21SMA63Y3Y19WQVNMWDdoZVU |
|
Definitely not a problem with the install. I didn't encounter your problem using your install. Are there any user account restrictions? @nollchr do the other laptops have this problem? |
|
no restrictions to my knowledge, can try uninstall/reinstall |
|
ah, the test file that was uploaded does work on my computer but this one initiates the crash (even after uninstall/reinstall of latest release): Stack Trace:com.thoughtworks.xstream.mapper.CannotResolveClassException: grip:Pipeline
