what's line 2724 of js/src/xpconnect/src/xpcwrappednative.cpp for you?

for modules/service.js line 593, could you indicate the source line text as well as which interface and method/attribute is being poked?

Seems like Weave 0.7, yes?

Comment 3

What is the full path of modules/service.js ?

modules/service.js should probably be in an extension directory in your profile.

https://developer.mozilla.org/en/Setting_up_extension_development_environment links to http://kb.mozillazine.org/Profile_folder

ok, so, 2724 isn't really a valid line to crash on. let's assume you're crashing on 2725.

Please print: callee, vtblIndex, paramCount, wantsOptArgc

   591         return Svc.Crypto.verifyPassphrase(
   592           privkey.payload.keyData, this.passphrase,
   593           privkey.payload.salt, privkey.payload.iv
   594         );

So, our choices for method calls are:

Crypto.verifyPassphrase:
Components.classes[/*Crypto*/
 "@labs.mozilla.com/Weave/Crypto;1"
].getService(
 Components.interfacesByID[/*IWeaveCrypto*/
  "{f4463043-315e-41f3-b779-82e900e6fffa)*/
 ]
)["verifyPassphrase"](...)

and:
privkey.payload.*

Based on a quick skim of weave, I *believe* that privkey.payload is a js object, which means we're talking about verifyPassphrase.

please also attach IWeaveCrypto.xpt (at some point, someone should run xpt_dump on it) -- sorry for dragging you through this, it's 1am and i'm in the bay area for TPAC. I will probably visit MoCo one of Today (Tuesday), Tomorrow (Wednesday) or Thursday, but I won't have much time.

It looks like this is a clash with an extension I am writing that also uses WeaveCrypto. I will look into it a little bit deeper soon. Closing as INVALID.
