Short description of error
I have objects for which I have keyframes for location changes as well as for texture changes like Alpha. However I can not see keyframes for only some objects in the Dope sheet view and Timeline also. In the screenshot you can see a selected object "ICE-ISO". This has a translation path assigned, however the Dope sheet is absolutely empty. I scrolled all up and down, there is only a red line in it. I can see the keyframes for other objects without problems also in this specific file.
Exact steps for others to reproduce the error
Unfortunately I can not say since which action this was happening. So I can not reproduce it for now.
