Bug ID: 389413
Summary: Krusader crashes when entering directories with read
errors
Product: krusader
Version: Git
Platform: Ubuntu Packages
OS: Linux
Status: UNCONFIRMED
Severity: normal
Priority: NOR
Component: general
Assignee: [email protected]
Reporter: [email protected]
Target Milestone: ---
I have a directory that throws some read errors when I perform an `ls` in this
dir. This is how the read erros look like:
"ls: cannot read symbolic link 'core': Protocol error"
Before you say "Well, your system is broken! Hahaha!", let me explain this in
more detail. First of all this is an mounted network resource that I don't
manage. So I'm not responsible for this bug. I just have to deal with it.
Secondly, several other file managers are more fault tolerant, e.g. Dolphin or
mc. I wish that Krusader would also just ignore those read errors and show me
all valid files and directories instead of crashing.
Here is the stacktrace (using the git version):
