Bugzilla Bug 275407

When running svn up, subversion segfaults as it accesses the wallet.  The
wallet appears, ask for you password, then subversion segfaults.  My kde
version is 4.2.4 and this entry would be a new entry to the wallet I believe
because my wallet was settings were recently reset.  The wallet does work in
other scenarios.

Temporary solution is to compile subversion without the kde use flag.

I am filing this as critical because the software is crashing, but feel free to
downgrade the severity.

Reproducible: Always

Steps to Reproduce:
1. Compile and setup kde 4.2.4
2. Compile subversion with kde use flag.
3. Open a terminal and cd to a svn repo.
4. Run an svn up on the repo.

Actual Results:  
subversion segfaults

Expected Results:  
updated the repository

Do you have some valuable backtrace to attach as well?

CC-ing upstream

(btw, who assigned it to KDE team :P)

i assigned kde because i thought it was probably a kde specific issue, i will
see if i can get a stack backtrace as well

if we need to move the bug to a more appropriate team please do so =0)

Rebuild dev-util/subversion and kde-base/kdelibs with:
CFLAGS="-ggdb3 -march=i686 -pipe"
CXXFLAGS="-ggdb3 -march=i686 -pipe"
FEATURES="nostrip"

Next attach the output of running:
gdb --args svn ${COMMAND} ${OPTIONS}
r

If you don't have 'gdb' program, then install sys-devel/gdb.

right now i dont't have source line numbers available, but after disassembly, i
think it's one of the wallet->...folder() method calls (presumably the first
one)
