Experiments are not listed in the Crash tool

Project Member Reported by w...@chromium.org, Jan 3 2018

Issue description

Chrome Version: Various; appears to affect at least as far back as M63.
OS: ChromeOS (not sure if it affects other platforms).

All the crash reports (across versions from M63 to M65) that I open show output under Fields->Experiments of the form:

Count 52
IDs 0 6a89113b-ccb9a6a5f4a17dfedbc38-cf4f6ead4a17df6c6887-f7b8f67e47f4f43b2dc5-9370259047f4f4562a9-78c337f0b72d7ce-612a79a3ff277-e1cc0f1475-3d47f4f4	AppBannerTriggering: Unknown Group

Alexei points out that this looks like the separators between the variation hashes are missing, preventing them from being correctly matched and reported.
 
Can you link to some sample reports that have an issue? I spot checked some reports on 65.0.3299.0 (latest canary) and the experiments show up.

Hmmm, it seems this isn't common to all reports, after all.

e.g. reports 28c57030bb9fdc07 and 25f80b4a80c88097 look fine, but reports 2f0d68100c2259ec, 675c5b877b13a29e and a172b2c2e6ba87fc are broken.


Looking at the "Product Data" section, you can see that the variations-N chunks are where the corruption starts, which likely means this is an issue with the client-side data rather than the server-side processing. In Chrome 65, the crash key system has been completely replaced, so I'd be curious to see if the issue continues there.
wez: Is this still an issue?
Status: WontFix (was: Untriaged)
Looking at some sample crashes from M68 they all look fine, so closing WontFix / obsolete for now.
