No, Don't need the entire Logcat as it would take Entropy time to look thru, But yea if you only post the lines with the Error's and everything else, it would help Entropy better to understand whats wrong.
Actually, too often people don't understand what is relevant and what isn't - so never try to censor it yourself. However don't post the whole thing as a code block, zip it up or attach as a text file.
IF it is something you can reliably reproduce, clear the logcat before you trigger the issue:
Code:
logcat -c
logcat -v time > blah.txt
