Bug 146124

Version:           1.4.1 (using KDE 3.3.1, compiled sources)
Compiler:          gcc version 3.3.4
OS:                Linux (i686) release 2.4.27

I don't know how to make this reproduce.  I'm not even certain that it is a Konsole issue.  But, I figured I'd tell you anyway.

Lately, I've been working with two Konsoles open, each with five tabs.  Nine of those tabs are involved in ssh sessions to a remote machine.  The tenth tab is just a regular terminal on the local machine.  I use most of the tabs very often, so I'm jumping around a bit between them.

Sometimes, I notice strange characters echoed into the terminal window.  Typically, I recognize them as related to something I've been doing, but I don't expect them to be in the terminal when and how they are there.  Here are some examples of the behavior:

1]  I run a program that prints some debugging output to stdout (the terminal).  Most of the time, everything goes as normal.  But, once in a while, some of the output from the program will end up entered into the command line.  It is as if I had copied and pasted (with the mouse, for example), the output from the program onto the command line.  At first, I thought I might have done that somehow.  But, I'm not really sure how I could have done that, even accidentally.  The mouse has three mouse buttons, no emulation, and the third is central scroll -- hard to paste and not realize it.  Plus, it was many lines of text that were sent to the command line -- just to highlight all that would have taken conscious effort.  I save 1000 lines of history, and they were almost all taken up.

2]  A portion of a man page showed up in the terminal window.  I had not accessed the man page recently, and didn't even recognize the program/file/etc. the page was written for.  But, I might have accessed it at some point and forgotten it.  For example, hitting "K" in vim will take you to a man page for the word under the cursor, if one exists.  It's possible I had done that accidentally.

3]  Bits of files that I've been working on (vim) get altered.  Typically, some portion gets added or deleted.  Again, at first I thought I was just being incredibly bad at typing/pasting.  But, then a file's contents disappeared entirely and was replaced by half of another file.  I'd had both files opened during the session just before I noticed.  While file changes like this can happen on the remote machine, they can also easily occur, in strange ways, if random text is echoed to a terminal window while vim is in command mode.  On the other hand, I -think- I remember exiting both files before backing them up (the backed up versions were fine), but it was late...

So far, this only seems to happen within/between ssh sessions to the remote server, which makes it likely to be a problem on the remote machine.  But, other users on that machine have not mentioned similar problems (I asked).  So, it might be on my end.  

I saw another bug listed that mentions text getting inappropriately highlighted when choosing a window.  Perhaps this is related, though I haven't noticed that particular behavior.
